/*	This is here for the "repair any errors" feature in the admin center.  It
	uses just two simple functions:

	void RepairBoards()
		- finds or repairs errors in the database to fix possible problems.
		- requires the admin_forum permission.
		- uses the raw_data sub template.
		- calls createSalvageArea() to create a new board, if necesary.
		- accessed by ?action=repairboards.

	void pauseRepairProcess(array to_fix, int max_substep = none)
		- show the not_done template to avoid CGI timeouts and similar.
		- called when 3 or more seconds have passed while searching for errors.
		- if max_substep is set, $_GET['substep'] / $max_substep is the percent
		  done this step is.

	array findForumErrors()
		- checks for errors in steps, until 5 seconds have passed.
		- keeps track of the errors it did find, so that the actual repair
		  won't have to recheck everything.
		- returns the array of errors found.

	void createSalvageArea()
		- creates a salvage board/category if one doesn't already exist.
		- uses the forum's default language, and checks based on that name.
