• The last.fm importer restart text should be clarified

https://community.metabrainz.org/t/problem-with-import-from-last-fm/454546

• The last.fm import page should mention somewhere that the import service will not work if the user's last.fm account is private (hidden recent listening information).

• The last.fm username input should remember the username so it doesn't have to be typed repeatedly.
