[Rhythmbox-devel] [PATCH] Adding support to azlyrics.com a lyric plugin.

[kirotawa <kirotawa gmail com>]

I'm user and passionate for Rhythmbox also a music lover. 
I miss sometimes a good support in lyrics plugin. Terra plugin is failing
these days, and summed to that its database is not so good. 

With this patch I'm adding support to another site that provides lyrics
IMHO  better than terra and others.  Would appreciate a patch review or 
a deny review/feedback.

Thanks.
