Booru-style tags & taxonomies

Note: #86 (switching to PostgreSQL) should be done first.

Pony.fm's taxonomies, in their current form, are too rigid to accurately describe all of the pony fandom's music.

Booru-style tags will be a powerful replacement for them as they'll make the following possible:

• multiple instances of the same "type" of tag (ie. track type or genre - a track could be a ponified track mashed up with a fan-made song)
• organically evolving tags, driven by the community (ie. users coming up with tags based on characters, themes, or anything else that's relevant to a track)
• tag implications ("orchestral dubstep" would show up in search results for "orchestral", "dubstep", and "orchestral dubstep" music)

It should be possible to organize tags in groups (like "genres" and "show songs") so special UI can exist for managing them and to make it possible to map them to the tags in downloadable files.

• [ ] implement tags in the backend
• [ ] convert genres into tags
• [ ] convert track types into tags
• [ ] convert whether a track is vocal or not into tags
• [ ] build admin UI for curating tags (will replace #20)
• [ ] build user-facing UI for searching by tags (tie-in with #1?)
• [ ] build user-facing UI for creating and editing tags

Consider building an IPLS (involved people list) ID3 tag out of the above data.

Genres need to be left in Please do not remove the genres

There needs to be both a tag and a genre system, so as to make it easy to search music by genre, and by tag. Genres need to be a fixed list that forces the user to pick one genre. Styles and such can then be expressed as tags.

It's possible we can implement required tags, would that alleviate your issue @westjgames?

I would honestly say that having a list of tags where at least one is required would be a better way to handle genres, and using tags for genres to keep search consistent and allow multi-genre tagging
