    [osx] store bundle path, relocate once, spaceguard
    
    Only generate config files that need absolute paths when it is
    detected that the bundle location has changed. Store the bundle
    location in ~/.config/banshee-1/app-bundle-location. Additionally
    remove the Mono Addins databases when we are relocated.
    
    Finally, until a better work around for Pango modules is found,
    the bundle path cannot have any spaces in it, since the resulting
    absolute path as written to pango.modules will contain a space,
    and pango will not properly parse this, so no modules will load
    and Banshee will not be able to render any text.
    
    If a space is detected in the bundle path, show a lame dialog
    telling the user how lame this is.
