Added "join signs" which will add players to an arena when they click on the sign.
Added /hg setsign <arena> command. Using this command will allow a sign to be clicked and chosen as the "join sign" for an arena.
Added message to player when they are sponsored letting them know they were sponsored.
Added /hg timeleft <arena> command which will show how much time left until deathmatch and/or end-game if either is turned on for that arena.
Added onStartPlayer command which is run for each player when a game starts.
Changed onLeaveGame command to only be run when a player exits or uses /hg leave.
Fixed onDeathmatch and onDeath commands overlapping as well as any potential command overlaps involving similar command names.
Beta version with limited support.
BUKKIT-2199 still a problem. Until fixed, players are teleported one tick apart so you will need at least 10 seconds of countdown to give all players a chance to be teleported in.
Some features not fully tested. Please report a ticket if you find a bug.
