- Added client side visualization of area restrictions

- Added an icon to the "Region control" menu item
- Changed the former TAccessLevelChangedPacket and the TLoginResponsePacket to add informations about the writeable areas
- Changed OnModifyUserPacket to update clients according to new accesslevel/area restrictions
- Changed OnModifyRegionPacket to update clients using that particular region
- Fixed UPacketHandlers.ValidateAccess to check the region bounds according to the PtInRect function
