Various things

Fixed arrest stick. Fixed taser (and formatted code a bit). Pressing F4
can now close the changeteam menu as well as open it. Modified 'list
get' code to be more reliable. Added a button to reset all gamemode
settings in the F3 admin tab (fixes #90). Changed UpdateRPNames to
RP:UpdateCustomNames. Custom names are now shared instead of clientside
(fixing a bug in /ooc). Pressing F3 can now close the menu as well as
open it. Police tab is now functional, can set/unset/view wanted status
on all players (fixes #47). Other police can now be arrested (in case of
abuse etc). Added RP.DefaultSettings for use mainly with
RP:ResetSettings().
