Album Search Results Changes

- mb findRelease
get additional info incl Date, Formats, Tracks, Rgid etc, pass to
searchresults
added optional artist to findrelease, if searching by album can now
enter album:artist in the search bar, went for this for now as I didn’t
want to change the design too much but maybe in the future we could
have 2 boxes, artist album and then there’s no need for the dropdown
artist, album

- base
position at search box and persist selected option (uses local storage)
when refreshing, useful if entering multiple albums
increased the search box size a little

- searchresults
album results - new fields from mb, fall back to cover art archive rgid
url if last.fm not found (should get more results), musicbrainz album
icon link, pass mb rgid to addReleaseById to redirect to album page
artist results - musicbrainz artist icon

- importer
addreleaseById - added rgid param to create the album record upfront
with status Loading if from searchresults

- webserve
redirect to album page using rgid from searchresults

- album
spinner while album is loading
