- Implement NtCreateKey using the new parse routine.

Browse source 
- NtOpenKey should only return the key handle if the operation was successful.
- Point to new parse routine, and rename it to CmParseKey instead of CmParseKey2 which was used during the test phase.
- Delete all of the "cm" directory, this code is now fully gone; the new Configuration Manager is in place.
- Move cm.h and cm_x.h to include/internal where they belong to and fix all their includers.
