	$type's accepted (pre-pend with AUTH_):

	VIEW, READ, POST, REPLY, EDIT, DELETE, STICKY, ANNOUNCE, VOTE, POLLCREATE



	Possible options ($type/forum_id combinations):



	* If you include a type and forum_id then a specific lookup will be done and

	the single result returned



	* If you set type to AUTH_ALL and specify a forum_id an array of all auth types

	will be returned



	* If you provide a forum_id a specific lookup on that forum will be done



	* If you set forum_id to AUTH_LIST_ALL and specify a type an array listing the

	results for all forums will be returned



	* If you set forum_id to AUTH_LIST_ALL and type to AUTH_ALL a multidimensional

	array containing the auth permissions for all types and all forums for that

	user is returned



	All results are returned as associative arrays, even when a single auth type is

	specified.



	If available you can send an array (either one or two dimensional) containing the

	forum auth levels, this will prevent the auth function having to do its own

	lookup
