20130319 - FreeDB support

[Dan Gravell]

This release has a number of improvements...

- FreeDB is now queried when a freeDbDiscId is sent. Example:

http://onemusicapi-beta.elasticbeanstalk.com/20130307/release?freeDbDiscId=4f06d108&track.1.offset=150&track.2.offset=16541&track.3.offset=30314&track.4.offset=46236&track.5.offset=62800&track.6.offset=79492&track.7.offset=95384&track.8.offset=112719&track.leadout.offset=131099&inc=images&maxResultCount=20

You can also query the /disc endpoint, useful for CD specific queries (e.g. for multi disc releases):

http://onemusicapi-beta.elasticbeanstalk.com/20130307/disc?freeDbDiscId=b60f8a0e&track.1.offset=150&track.2.offset=17590&track.3.offset=31785&track.4.offset=49250&track.5.offset=62055&track.6.offset=79095&track.7.offset=101640&track.8.offset=118420&track.9.offset=140255&track.10.offset=167317&track.11.offset=171027&track.12.offset=186015&track.13.offset=222720&track.14.offset=247655&track.leadout.offset=298515&inc=images&maxResultCount=20

- CD TOC information sent in the track.n.offset parameters are used to further validate matches, but only when minCertainty=1 (the default)

- FreeDB is linked to Discogs and MusicBrainz to ensure further information, such as cover art, is discovered for a FreeDB disc ID

- Acoustid searches can now be made for the /disc/ endpoint
