Fixed a very simple logic bug, whoops.
Updated StBukkitLib dependency version.
Actually return something useful.
Added a getter for the 'games' command handler and moved the sign manager defaults to a method in GgSignManager.
Added a parameter for giving a sign extra data on creation.
Finished up the join sign type.
If the players for a game instance aren't being tracked, return the game instance's owner's players.
Added leave command and made it so sneak+clicking on a join sign acts as a leave sign.
