Have "Last.fm Tags" plugin also fetch a user's tags #230
Description
From https://tickets.metabrainz.org/browse/PICARD-495
The "Last.fm Tags" plugin (http://wiki.musicbrainz.org/PicardQt/Plugins) is very cool.
A cool additional feature would be an option to fetch the tags set by a given user. Hence I'd be able to tag my music with the tags I set on last.fm.
I tried to modify the plugin to achieve this, and miserably failed. :/
