Fixed a bug where players would not get their weapons back after being unarrested during a sit.
Fixed an error to do with physgun pickups.
Blocked /ooc, /a, //, /advert, /w, /y, /pm, /me, /broadcast, /radio and /g on DarkRP for non-staff during a sit.
Better compatibility with non-DarkRP gamemodes.
Only non-staff players can have their country and OS seen by staff. (Staff cannot see eachother's, players cannot see staffs', players cannot see players')
