Include MusicBrainz Release URL in log output

[Freso]

This also passes all metadata to the result object, giving loggers a lot more (release) metadata to work with, in case custom, “3rd party” loggers (or even ourselves in the future!) want to do something more fancy or expansive with the metadata in the log file.

Fixes #381

[MerlijnWajer]

You might want to add metadata here https://github.com/whipper-team/whipper/blob/master/whipper/result/result.py#L67 to RipResult.

[Freso]

@MerlijnWajer But there's nothing there getting the metadata? self.program.result in cd.py is an instance of RipResult. cd.CD_.do() is the method that's responsible for populating the RipResult class instance(s) with (meta)data currently.

[Freso]

@MerlijnWajer Done. :)
