Support for embedded cue files as directory

[sluedecke]

Feature request

Right now embedded cuesheets (tag cuesheet set to the content of a cuesheet file) are supported, but the content can not be searched for, because the EmbeddedCuePlaylistPlugin does not yet support the as_directory configuration parameter.

So I kindly request to have the playlist plugin for embedded cuesheets support the as_directory = 'true' parameter.

This is a quite crude patch which makes it work for me, but it probably breaks a lot of other things ...

PS: sorry for the noise in the patch, my editor very eagerly reformatted all files I edit and some of that is still in the patch as noise.
