Cooldowns don't expire

[JorenCombs]

Was playing around with current MultiHome jar and noticed that, if cooldown is used, after the player has an entry in the cooldown flatfile, the counter will count down to 1 and stay there. They will never be able to /home again.

This appears to be because the CoolDownManager's removeCooldown method is never called, and therefore when MultiHomeCommands checks to see if a player has a cooldown, it will always get one even if the cooldown already expired. As long as the getCooldown does not return null, then the player cannot /home.
