Interactive import session should offer a "Retry" choice in case of MusicBrainz server error

When importing using the autotagger, sometimes the MusicBrainz server is not reachable, which gives an error like:
`Error: MusicBrainz not reachable in get release ...`
In case the import session is interactive, the user gets prompted with the usual choice dialog. It would be very nice if an extra option `[R]etry` is added in this situation, since quite often it's not server downtime but just hickups (also possibly on your own end). Now I have to skip the album in case I'd like to retry the autotagging process, which is especially tedious if it concerns a mass import.

Would love to hear your thoughts.
