WhosAFK

Notable changes:

• AFK mode turns the player invincible. All player damage events that the player takes are cancelled. This shouldn't be a cheaty feature because the player is AFK, and, since the plugin automatically removes the AFK status of the player if the player moves, the player can't be lying about being AFK unless the player is just chatting.
• Turning the head around does not remove AFK status. This is useful, for example, if the user bumps the mouse right after typing /afk
• Operators who think a player is AFK can give the player AFK status by typing /afk <player's name>. This is supposed to be a workaround until I can get the automatic AFK feature working.

• There is still no automatic AFK
• Chatting does not remove AFK status
