Chris@76: 
Chris@76: 	void LockTopic()
Chris@76: 		- locks a topic, toggles between locked/unlocked/admin locked.
Chris@76: 		- only admins can unlock topics locked by other admins.
Chris@76: 		- requires the lock_own or lock_any permission.
Chris@76: 		- logs the action to the moderator log.
Chris@76: 		- returns to the topic after it is done.
Chris@76: 		- accessed via ?action=lock.
Chris@76: 
Chris@76: 	void Sticky()
Chris@76: 		- stickies a topic - toggles between sticky and normal.
Chris@76: 		- requires the make_sticky permission.
Chris@76: 		- adds an entry to the moderator log.
Chris@76: 		- when done, sends the user back to the topic.
Chris@76: 		- accessed via ?action=sticky.
