Title: Allow selection of source for genre information (ie - artist vs album)

If config is set to:

```yaml
lastgenre:
source: artist
```

The genre will be fetched for the artist, rather than the album. This
allows for filesystem org like:

genre/artist/album

Currently defaults to previous behaviour for anything other than
`artist`
