I claim: 1. An insert cylinder cabinet cam lock, comprising: an elongated cylinder housing defining an exposed front end keyway aperture, a main body, and a distal rear end adapted for removable receipt of a conventional insert deadbolt cylinder; a substantially cylindrical cam driver having a forward end adapted for cooperative receipt in the deadbolt cylinder and a distal end adapted to receive and drive a cam bolt; a tailcap having spaced-apart sidewalls defining an open front end and an internal cavity adapted to mate with the cylinder housing rear end, and a planar rear wall defining a hub for journaling the cam driver for rotary motion; a cam bolt removably journalled to the cam driver for rotation therewith; and, removeable cam bolt rotary limitation means for securing the tailcap to the cylinder housing and for limiting rotation of the cam bolt thorough a prescribed range. 2. The cam lock of claim 1, wherein the cylinder housing rear end has a circumferential rebate and the tailcap has a corresponding circumferential flange sized for receipt on the rebate so that the cylinder housing and tailcap have a substantially continuous surface on at least a portion thereof and synchronized external threads on the continuous surface. 3. The cam lock of claim 1, wherein the cylinder housing has a plurality of axial treaded bores in the rear end thereof for alternate receipt of the cam bolt rotary limitation means and the tailcap rear wall defines corresponding apertures in registration therewith for passage therethrough of the cam bolt rotary limitation means. 4. The cam lock of claim 3, wherein the cam bolt rotary limitation means is a pin having a cooperatively threaded portion for receipt in one of the threaded bores and a circumferential shoulder for urging against the tailcap rear wall. 5. The cam lock of claim 1, wherein the cam driver has a radially extending circumferential flange for axially rearwardly restraining the cam driver. 6. The cam lock of claim 5, wherein the tailcap has a circumferential groove about the cam hub for bearing the cam driver flange. 7. The cam lock of claim 1, wherein the cam driver forward end has a hemicylindrical axial protrusion including a central bulge adapted for receipt in the deadbolt cylinder. 8. The cam lock of claim 7, including a low-friction washer positioned about the cam driver axial protrusion and between the cam driver flange and the deadbolt cylinder. 9. The cam lock of claim 1, including a lazy cam driver journaled for rotation with the cam driver rear end and having cam bolt drive means for driving the cam bolt. 10. The cam lock of claim 9, wherein the bolt includes a transverse pin for cooperative engagement with the lazy cam bolt drive means. 11. An insert cylinder cabinet cam lock, comprising: a cylinder housing defining an exposed front end keyway aperture, a main body, and a distal rear end adapted for removable receipt of an insert deadbolt cylinder; a cam driver having a forward end adapted for cooperative receipt in the deadbolt cylinder and a distal end adapted to receive and drive a cam bolt; a tailcap having spaced-apart sidewalls defining an internal cavity adapted to mate with the cylinder housing rear end, and a rear wall defining a hub for journaling the cam driver for rotary motion; a cam bolt removably journalled to the cam driver for rotation therewith; and, cam bolt rotary limitation means for securing the tailcap to the cylinder housing and for limiting rotation of the cam bolt through a prescribed range. 12. The cam lock of claim 11, wherein the cylinder housing rear end has a circumferential rebate and the tailcap has a corresponding circumferential flange sized for receipt on the rebate so that the cylinder housing and tailcap have a substantially continuous surface on at least a portion thereof and synchronized external threads on the continuous surface. 13. The cam lock of claim 11, wherein the cylinder housing has an axial treaded bore in the rear end thereof for receipt of the cam bolt rotary limitation means and the tailcap rear wall defines a corresponding aperture in registration therewith for passage of the cam bolt rotary limitation means. 14. The cam lock of claim 13, wherein the cam bolt rotary limitation means is a pin having a cooperatively threaded portion for receipt in the threaded bore and a circumferential shoulder for urging against the tailcap rear wall. 15. The cam lock of claim 11, wherein the cam driver has a circumferential flange for axially restraining the cam driver. 16. The cam lock of claim 15, wherein the tailcap has a circumferential groove about the cam hub for bearing the cam driver flange. 17. The cam lock of claim 11, wherein the cam driver forward end has a hemicylindrical axial protrusion adapted for receipt in the deadbolt cylinder. 18. The cam lock of claim 17, including a low-friction washer positioned about the cam driver axial protrusion and between the cam driver flange and the deadbolt cylinder. 19. The cam lock of claim 11, including a lazy cam driver journalled for rotation with the cam driver rear end and having drive means for driving the cam bolt. 20. The cam lock of claim 19, wherein the bolt includes a transverse pin for cooperative engagement with the lazy cam drive means. 21. An insert cylinder cabinet cam lock, comprising: an elongated cylinder housing defining an exposed front end aperture, a main body, and a distal rear end, the cylinder housing being adapted for removable receipt of a conventional insert deadbolt cylinder; a substantially cylindrical cam driver having a forward end adapted for cooperation with the deadbolt cylinder and a distal end adapted to receive and drive a cam bolt; a tailcap defining an open front end and an internal cavity adapted to mate with the cylinder housing rear end, and a planar rear wall defining a hub for journaling the cam driver for rotary motion; a cam bolt removably journalled to the cam driver for rotation therewith; and, a removeable cam bolt limiter for limiting rotation of the cam bolt thorough a prescribed range.
