Allow excluding album name from desktop notifications

Some desktop notification software doesn't parse newlines very well, e.g. dunst, where allowing '\n' causes a lot of dead space for me, and if you disable it, everything is on one line and harder to read. Also, some users might want this...maybe. I don't know. I do, anyway. It's a super small mod so I just did it instead of filing a request.

Note; this is ported from my modification to the debian package and works for me. Please ensure it works for you, I don't want to break anything.
