Bug#677235: gnome-sushi: please update to use libmusicbrainz5

[Jon Dowland]

Hi,

Patch applies fine and sushi builds.  I tried current unstable and then a
patched version. 

I haven't managed to provoke that code to run successfully with either version.

I'm getting 'Unable to fetch the Amazon cover art uri from MusicBrainz: Error
getting the ASIN from MusicBrainz' for anything I've tried, with either
version.

I'll try poking around more in the code.
