/*	This file contains the functions required to move topics from one board to
	another board.

	void MoveTopic()
		- is called to allow moderator to give reason for topic move.
		- must be called with a topic specified.
		- uses the MoveTopic template and main sub template.
		- if the member is the topic starter requires the move_own permission,
		  otherwise the move_any permission.
		- is accessed via ?action=movetopic.

	void MoveTopic2()
		- is called on the submit of MoveTopic.
		- requires the use of the Subs-Post.php file.
		- logs that topics have been moved in the moderation log.
		- if the member is the topic starter requires the move_own permission,
		  otherwise requires the move_any permission.
		- upon successful completion redirects to message index.
		- is accessed via ?action=movetopic2.

	void moveTopics(array topics, int destination_board)
		- performs the changes needed to move topics to new boards.
		- topics is an array of the topics to move, and destination_board is
		  where they should be moved to.
		- updates message, topic and calendar statistics.
		- does not check permissions. (assumes they have been checked!)
