several changes in this checkin
* added REG_OPEN_HKCR for supporting regedit.exe
* All data n a REGISTRY_VALUE is stored to a pointer now
* fixed REG_INFO to correctly display data when double clicking on
and entry in the registry editor
* Will now enumerate installed driver_info_3 data
* fixed numerous bugs related to pointer offsets, memory issues, etc..
in the registry routines
* added a simple caching mechanism to fetch_reg_[keys|values]_specific()
All that is left now is to enumerate PrinterData and I will have finished
what I started out to do....
