music: revamp excluded into music dirs

Completely rework the excluded directory system into a new
"Music Folders" system.

This is implemented alongside a new "Include" mode. This mode
allows the user to restrict music indexing to a parsicular folder.
I've been reluctant to add this feature, as having two separate
options seemed bad. This resolves it by effectively packing whether
to include/exclude directories into a single option.

Resolves #154.
