We claim: 1. A fully-detachable, self-contained, fluid-tight, gravitational flow fluid dispensing device comprising: a fluid reservoir having a central opening; a valve cap covering the central opening in the fluid reservoir, the valve cap containing a controllable, normally closed, gravitational flow fluid poppet valve, the valve comprising a flex dome sealing and biasing member for sealing the valve from leakage during operation and biasing the poppet valve into a normally-closed position; retaining mechanism for retaining the valve cap over the central opening in the fluid reservoir; an elongated fluid path for communicating fluid from the reservoir, through the normally-closed fluid valve, to a nozzle portion; and a nozzle portion for dispensing fluid, wherein the fully-detachable, self-contained, fluid-tight gravitational flow fluid dispensing device is detachably coupled to a tool for applying the fluid to a hard surface. 2. The fluid dispensing device of claim 1, further comprising a mechanism for coupling the nozzle portion to the tool. 3. The fluid dispensing device of claim 1, wherein the fluid path comprises a portion of tubing. 4. The fluid dispensing device of claim 1, wherein the fluid path comprises a portion of flexible tubing. 5. The fluid dispensing device of claim 1, further comprising a venting system for venting the fluid reservoir while dispensing fluid. 6. The fluid dispensing device of claim 5 in which the venting system comprises an opening extending from an atmosphere in which the device is being used through the valve cap and into the fluid reservoir. 7. The fluid dispensing device of claim 6 in which the venting system further comprises a dip tube extending from the opening through the valve cap into the reservoir. 8. The fluid dispensing device of claim 7 in which the venting system further comprises a check valve mounted onto the dip tube extending into the reservoir. 9. The fluid dispensing device of claim 6 in which the venting system further comprises a check valve positioned between the opening through the valve cap and the reservoir. 10. The fluid dispensing device of claim 1, in which the nozzle portion snap fits onto a tool. 11. The fluid dispensing device of claim 1, in which the nozzle portion is shaped to be retained onto a tool. 12. The fluid dispensing device of claim 1, further comprising a mechanism for detachably coupling the nozzle portion to the tool. 13. A fully-detachable, self-contained, fluid-tight gravitational flow fluid dispensing device comprising: a fluid reservoir having a central opening; a valve cap covering the central opening in the fluid reservoir, the valve cap containing a normally closed, gravitational flow fluid poppet valve, the valve comprising a flex dome sealing and biasing member for sealing the valve from leakage during operation and biasing the poppet valve into a normally-closed position; retaining mechanism for retaining the valve cap over the central opening in the fluid reservoir; an elongated fluid path for communicating fluid from the reservoir, through the normally-closed fluid valve, to a nozzle portion; and a nozzle portion for dispensing fluid and means for detachably coupling the nozzle to a tool, wherein the fully-detachable, self-contained, fluid-tight fluid dispensing device is detachably coupled to a tool for applying the fluid to a hard surface. 14. A fully-detachable, self-contained, fluid-tight gravitational flow fluid dispensing device comprising: a fluid reservoir having a central opening; a valve cap covering the central opening in the fluid reservoir, the valve cap containing a normally closed, gravitational flow fluid poppet valve biased closed with a flex dome sealing and biasing member; retaining mechanism for retaining the valve cap over the central opening in the fluid reservoir; an elongated fluid path for communicating fluid from the reservoir, through the normally-closed fluid valve, to a nozzle portion; and a nozzle portion for dispensing fluid, wherein the fully-detachable, self-contained, fluid-tight fluid dispensing device is detachably coupled to a tool for applying the fluid to a hard surface. 15. A fully-detachable, self-contained, fluid-tight fluid dispensing device comprising: a fluid reservoir having a central opening; a valve cap covering the central opening in the fluid reservoir, the valve cap containing a normally closed, gravitational flow fluid poppet valve, the valve comprising a flex dome sealing and biasing member for sealing the valve from leakage during operation and biasing the poppet valve into a normally-closed position; retaining mechanism for retaining the valve cap over the central opening in the fluid reservoir; an elongated fluid path for communicating fluid from the reservoir, through the normally-closed fluid valve, to a nozzle portion; a venting system comprising a dip tube defining an opening extending from an atmosphere in which the device is being used through the valve cap and into the fluid reservoir; and a nozzle portion for dispensing fluid, wherein the fully-detachable, self-contained, fluid-tight fluid dispensing device is detachably coupled to a tool for applying the fluid to a hard surface. 16. A self-contained, fluid-tight, fluid dispensing device for detachably coupling to a hard-surface cleaning tool, the fluid dispensing device comprising: a fluid reservoir coupled to a handle portion of the cleaning tool, the fluid reservoir having a valve cap covering an opening in the fluid reservoir, the valve cap containing a normally-closed, gravitational-feed, self-venting fluid poppet valve, the valve comprising a flex dome sealing and biasing member for sealing the valve from leakage during operation and biasing the poppet valve into a normally-closed position; a fluid nozzle portion which can be coupled adjacent a cleaning head portion of the cleaning tool; and an elongated fluid path communicating fluid from the reservoir, through the fluid valve, to the nozzle portion. 17. A method of use of a self-contained, fluid-tight, fluid dispensing device for detachably coupling to a hard-surface cleaning tool, the fluid dispensing device comprising: (1) a fluid reservoir having a valve cap covering an opening in the fluid reservoir, the valve cap containing a normally-closed, gravitational-feed, self-venting fluid poppet valve, the valve comprising a flex dome sealing and biasing member for sealing the valve from leakage during operation and biasing the poppet valve into a normally-closed position; (2) a fluid nozzle portion; and (3) an elongated fluid path communicating fluid from the reservoir, through the fluid valve, to the nozzle portion; the method comprising the following steps: coupling the fluid reservoir to a handle portion of a cleaning tool; coupling the fluid nozzle portion adjacent a cleaning head portion of the cleaning tool; and controllably dispensing fluid from the reservoir.
