Checks an array of MIME types against a list of allowed types.

WordPress ships with a set of allowed upload filetypes, which is defined in wp-includes/functions.php in get_allowed_mime_types(). This function is used to filter that list against the filetypes allowed provided by Multisite Super Admins at wp-admin/network/settings.php.
