An assignment is now an ordered list of albums (e.g. one vinyl compiling two EPs that are separate releases in the library). Albums move to their own table, with a migration for existing databases. The scan and lookup responses return an albums list instead of the single artist/album/uri fields. The tag page lists its albums with up, down and remove, and search results get an Add button.
