set_style now accepts an array containing a list of paths, e.g. array( 'ext/foo/bar/styles', 'styles'). Default: array('styles') Using this option allows us to set the style based on the user's preferred style (including the full tree), but use one or more base directories to add the paths from. The main use for this ability is so that extensions can call set_style, including their path and the phpBB styles path (or any others) and have their template files loaded from those directories (in the order given).
