[Enhancement] Edit metadata from within application

[wisetrap11]

I'm really enjoying this application, but there is something I wish it had-- Editing metadata. As far as I'm aware, editing metadata is only available through the iTunes application, and that's a bit inconvenient, seeing as I've been trying out this app as a potential replacement to the iTunes application.

If this is something possible to add to Cider itself, then I'd certainly enjoy having it be added.
