Reduce GConf roundtrips

Browse source 
metacity tries to do the right thing, by preloading all the relevant
directories before getting the keys one-by-one, but GConfClient isn't actually
smart enough to avoid server roundtrips in this case. That should certainly be
fixed in GConf.

In the meantime, here is a patch that reworks the metacity prefs initialization
to avoid roundtrips for individual keys anyway, by using
gconf_client_all_keys().
