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....
