weather: Stop accessing app settings directly

Our current Weather integration depends on poking around the app's
settings, which we cannot do when the app is sandboxed (as its
filesystem is "hidden away" in a container in that case).

So instead, use our own GSettings schema for the settings, and sync
it with GNOME Weather via a custom D-Bus interface.
