Refactored map voting

Now contained in the plugin instead of spewed around core files.

Also added vote counters to the buttons for each map in the vote menu to
make seeing how many votes a map has easier.
Enforced password mode

Kicks out anyone that got in when the server's supposed to be locked
without access to sh_reservedslot.
Ready room plugin ignores AFK

Stops the fun back and forth fight between the two plugins when AFK kick
is set to move them to the ready room on warn.
Fixed some more conflicts
