    vimeo: Don't leak cache directories
    
    Temporary cache directories were never removed on exit because
    an instance of GrlNetWc was never unref'ed because a GVimeo instance
    was never unref'ed because GrlVimeoSource lacked a finalize method.
    
    Add a finalize method to remove empty cache directories on exit.
