Tag Files With Genre

[da2ce7]

All downloaded files from Bandcamp are without Genre.

Add support for extracting the Genre from the album's 'tags', then update the tags of the music files with the appropriate genre.

Neat idea! However this would mean being able to edit the tags of any music file type (mp3, vorbis, etc.) supported by Bandcamp. After a quick search I found jaudiotagger that could play this role: http://www.jthink.net/jaudiotagger/ but it would need to be investigated a little more.

Not sure whether I will be able to find time do this, but if someone wants to try and submit a PR, please do!
