1. A ski binding for fastening a ski boot with a firm or flexible sole onto a ski, the ski binding comprises: a forefoot-fixing module with a mounting section for mounting onto a ski, anda movable section that can be rotated or pivoted relative to the mounting section in such a way that at least a rear end of the movable section can be lifted off the ski; anda support for the heel of the ski boot;wherein the movable section of the forefoot-fixing module comprises,a front receptacle for receiving a front end of the ski boot, in particular a front sole extension, anda rear receptacle, which is suitable for receiving an engagement element situated on or in the underside or to the side of the sole of the ski boot,wherein the front and rear receptacle are together suitable for fastening a front section of the ski boot in the forefoot-fixing module, and in which the front and rear receptacle of the movable section of the forefoot-fixing module are fastened to a rigid plate or a rigid frame,wherein at least one of the front and rear receptacles is associated with a releasing mechanism, which causes the front section of the ski boot to be released from the forefoot-fixing module once a threshold has been exceeded by a torque of the ski boot relative to the forefoot-fixing module, which torque corresponds to a rotation of the ski boot in the sole plane, wherein the ski binding provides one or more of the following,a Telemark downhill mode, in which the movable section of the forefoot-fixing module can be rotated or pivoted in relation to the mounting section without the front section of the ski boot received therein being bent or kinked, and in which a spring mechanism generates a restoring force, in particular a restoring torque, between the movable section and the mounting section, which counteracts a lifting of the rear end of the movable section of the forefoot-fixing module from the ski,a cross-country or climbing mode, in which the movable section of the forefoot-fixing module can be rotated or pivoted in relation to the mounting section without the front section of the ski boot received therein being bent or kinked, wherein the mechanical coupling between the movable section and the mounting section is such that, when the movable section of the forefoot-fixing module rotates or pivots by 35°, a restoring torque between the movable section and the mounting section generates a torque of less than 5 Nm. 2. The ski binding according to claim 1, in which the spring mechanism comprises a compression spring which is situated between a front and a rear spring stop, wherein, during operation, the position of the rear spring stop is fixed in place relative to the mounting section, and the movable section of the forefoot-fixing module is configured to interact with the front spring stop in such a way that the front spring stop is pushed towards the rear spring stop against a preloading of said compression spring when the rear end of the movable section of the forefoot-fixing module is moved away from the ski, wherein the position of the second spring stop can be adjusted to thereby set a restoring force or restoring torque of the spring mechanism according to the physical constitution of the skier, the terrain to be traversed and/or personal preferences. 3. The ski binding according to claim 1, in which the spring constant of the spring mechanism is chosen such that the restoring force in the Telemark downhill mode generates a torque of at least 15 Nm when the movable section of the forefoot-fixing module rotates or pivots by 35° out of the position in which the heel of the ski boot rests on the support. 4. The ski binding according to claim 1, in which the spring mechanism can be switched between at least two preset configurations, in which differing levels of restoring forces or restoring torques are generated for the Telemark downhill mode. 5. The ski binding according to claim 1, in which the spring mechanism has allocated to it a control, with which the spring mechanism can be preloaded to generate the restoring force or restoring torque, or can be preloaded while switching between said at least two preset configurations. 6. The ski binding according to claim 5, wherein the control preferably takes the form of a preloading lever, that simultaneously serves as a platform for the ski boot. 7. The ski binding according to claim 1, in which the spring mechanism comprises a compression spring, which is situated under the sole of a ski boot when received in the ski binding. 8. The ski binding according to claim 6, wherein the preloading lever accommodates an additional lever, which can interact with a section of the spring mechanism in such a way as to convert a rotating motion of the preloading lever into a preloading motion of the spring mechanism, wherein the additional lever runs through a maximum preloading dead point while preloading the spring mechanism. 9. The ski binding according to claim 1, in which at least one of the front and rear receptacles comprises at least one claw-like element, which can be moved between an open and closed position, wherein the claw-like element, when in its closed position, is suitable for engaging around or engaging into the front end of the ski boot or said engagement element, wherein the claw-like element is biased into the closed position, and wherein said release mechanism exhibits a first cam surface or abutment surface, which is associated with the receptacle, in particular with the claw-like element,wherein the first cam surface or abutment surface is designed and situated to interact with a ski-boot-fixed release element in such a way that the claw-like element can be moved into the open position by means of the ski-boot-fixed release element and the first cam surface or abutment surface when rotating the ski boot in the sole plane. 10. The ski binding according to claim 9, in which the ski-boot-fixed release element is formed by a portion of said engagement element, in particular by a cam surface or abutment surface provided on the engagement element. 11. The ski binding according to claim 9, in which the front or rear receptacle exhibits two of said claw-like elements, of which a first can be moved into the open position by inwardly rotating the ski boot, and a second by outwardly rotating the ski boot. 12. The ski binding according to claim 11, wherein the torque of the ski boot in relation to the forefoot-fixing module required for moving the claw-like element into the open position is variably adjustable for the first and second claw-like elements so that the torque required to open the first claw-like element is smaller than the torque required to open the second claw-like element. 13. The ski binding according to claim 9, in which the claw-like element can pivot between the closed and open position. 14. The ski binding according to claim 9, in which the release mechanism comprises a second cam surface or abutment surface, which is associated with the claw-like element, wherein the second cam surface or abutment surface is configured to interact with the ski-boot-fixed release element in such a way that a force exerted by the ski-boot-fixed engagement element perpendicular to the sole plane supports or counteracts said preloading force of the claw-like element in the closed position in such a way that an upward pulling force directed perpendicular to the sole plane counteracts said preloading force of the claw-like element in its closed position. 15. The ski binding according to claim 1, in which the movable section is joined by way of a roller bearing or mechanical linkage with the mounting section of the forefoot-fixing module in such a way that the movable section can be moved in relation to the mounting section so that a pure rotating or pivoting motion overlaps with a translational motion, in order to facilitate a physiologically favorable rolling of the forefoot.
