Implemented hooks and base privilege system:
New privileges are in disable_sv.lua and mute_sv.lua
fgtadmin.users is now using an associative array with a key of the users steamid
Added GetPlayerPrivileges() which will return a table of privileges the targetPlayer has
Added Player[Add/Remoev]Privilege() which will grant/deny/revoke/inherit a privilege to a player. Returns nothing, see disable_sv.lua
