Un-weight artists without much music

[treyhunner]

Artists who who don't have a full CC album should be noted as less important (marked as dormant, zombie, or a better term).

We could search the FreeMusicArchive API and find artists without albums like this:

http://freemusicarchive.org/api/get/albums.json?api_key=<key>&artist_id=2908

Maybe we could create a model to store API responses for FreeMusicArchive artist albums or tracks. We could hide/disable artists with less than three tracks.

Track count can now be stored in artists.Hyperlink. Rather than 'un-weight' artists, we're highlighting artists we know have at least 3 tracks. The results will improve as the data collection efforts (#28, #24) are underway.
