- Changed a few leftover NPC IDs to constants
- Note: we're still missing support for mob sprite constants, so the
  NPCs using mob sprites are still not converted.

pc_groups interfaced

The last file without a interface is now no more (date.h doesn't count :P).
Modified the way permissions are stored in order to enable plugins to be able to create permissions ( pcg->add_permission("name") [returns permission key] ).
Special Thanks to Haruna!
Closes #121
