lastfm 1.3.1.0 msk1

This fixes a few bugs, especially in the browser-select patch. It also adds two new patches: one reduces the cpu load, the other now lets the client support multiple audio output plugins. See the changelog for details.

The multi-sound patch is in the unsupported category because it's currently way too invasive to put in the Debian package. It works well for me, though. And maybe upstream will eventually decide to apply it.
