Add support for Album view

Add support for Album view

Included album view as an optional setting.  Can extend this by adding a
"{description}/{controller method}" entry to the AvailableMusicViews
FormStrings entry (multiple options should be comma delimited).  You can
then add the {controller method} to the MusicLibraryController and a
related view.  The menu will automatically switch based on the saved
setting.
