Log:
[CMBATT]
 - Add initial cmbatt driver which mostly stubs
 - All it does right now is register a battery device with the battc driver
[BATTC]
 - Add a nearly complete battc driver (the only stuff missing is WMI)
 - Tested with our stubbed cmbatt driver but testing on Windows would be nice too
[BATTERY.INF]
 - Added battery.inf to install battery devices
[MISC]
 - Add cmbatt.sys, battc.sys, and battery.inf to bootcd
 - We still need to implement compbatt.sys
 - PS: Janderwald, you stole my commit number ;)
