19 void LockTopic()
20 - locks a topic, toggles between locked/unlocked/admin locked.
21 - only admins can unlock topics locked by other admins.
22 - requires the lock_own or lock_any permission.
23 - logs the action to the moderator log.
24 - returns to the topic after it is done.
25 - accessed via ?action=lock.
26
27 void Sticky()
28 - stickies a topic - toggles between sticky and normal.
29 - requires the make_sticky permission.
30 - adds an entry to the moderator log.
31 - when done, sends the user back to the topic.
32 - accessed via ?action=sticky.
