Last.fm's Love/Ban actions are currently available when playing a radio stream from Last.fm.

This patch adds support for Love/Ban actions to Banshee when playing any song with artist and track tags. When a song is loaded (playing or paused), if an user is connected to Last.fm, you should now see smileys on the top-right part of the client. Otherwise, they disappear.

Here is the ChangeLog:

2008-10-21  Warren Seine  <warren.seine@gmail.com>

	Add support for Audioscrobbler Love/Ban actions on non-radio
	source.

	* src/Extensions/Banshee.Lastfm/Banshee.Lastfm.Audioscrobbler/
	AudioscrobblerActions.cs: New. Separate GUI from service.

	* src/Extensions/Banshee.Lastfm/Banshee.Lastfm.Audioscrobbler/AudioscrobblerService.cs:
	* src/Extensions/Banshee.Lastfm/Banshee.Lastfm.Radio/LastfmActions.cs:
	Move Love/Ban actions to Banshee.Lastfm.Audioscrobbler instead
	of Banshee.Lastfm.Radio. Radio and scrobbling work separately.

	* src/Extensions/Banshee.Lastfm/Banshee.Lastfm.csproj:
	* src/Extensions/Banshee.Lastfm/Makefile.am: Updated with new file.

	* src/Extensions/Banshee.Lastfm/Resources/GlobalUI.xml:
	* src/Extensions/Banshee.Lastfm/Resources/LastfmTrackActions.xml:
	Update GUI to show the Love/Ban smiley/buttons even if the
	current source is local (appears if connected to Last.fm and
	having a song loaded).

	Still a small problem in the NotificationArea: the Love/Ban entries
	do not appear in their placeholder. Looks like a bug cause by
	the Audioscrobbler plugin being loaded before the NotificationArea
	plugin.

	* src/Libraries/Lastfm/Lastfm/AudioscrobblerConnection.cs:
	Change enum State to AudioscrobblerState (for coherence with
	RadioConnection.cs).
	Add handler on Audioscrobbler state change.
