    Paths: Allow different names for system vs user paths
    
    Banshee is renaming most everything from banshee-1 to banshee, with the
    exception of the ~/.config and ~/.cache directories.
    
    Add UserApplicationName property, which defaults to ApplicationName, but
    can be set so that the app cache and config/data directories can be
    "banshee-1" while the system directories can be "banshee".
