MusicBrainz improvements

[Jared]

Hello.  I've begun using musicbrainz more as a source of info for my 
collection, moving away from discogs.  But there are a couple features I 
miss from the discogs data source.  Wanted to request adding them, if 
possible.

1. Search by catalog number.  This currently isn't found by either the 
keyword or UPS/EAN search.  I haven't messed with the API much, but I 
know it's possible to perform an advanced search through the web UI to 
query by catalog number:

https://musicbrainz.org/search?type=release&method=advanced&query=catno:%22%s%22

Presumably something like that can be done via API as well.

2. "Search" by release UUID.  This would just directly pull the 
referenced release if already known instead of having to filter through 
search results.  Similar to searching for the unique release number as a 
discogs keyword.

3. Display a MusicBrainz Link to the release page.  This is convenient 
for being able to view details about a release and comparing versions 
before importing.

4. Include and populate MusicBrainz Link as a collection field, similar 
to the Discogs Link.

Thanks for the consideration!  Let me know if you have any questions 
that I could potentially better clarify.
