    lib: Fix memory and D-Bus match rule leaks
    
    From #3:
    > The GWeatherInfo settings object is never freed leading not only
    > to a memory leak, but also to a dbus match rule leak, which on
    > the system bus can quickly result in reaching the maximum amount
    > of allowed match rules. See gnome-shell#96.
