NMRemoteSettings duplicates a bunch of NMObject's functionality that it doesn't need to. In libnm-glib, it wouldn't have been possible to port NMRemoteSettings to NMObject without breaking ABI, but now in libnm we can do that. As a side effect of this, NMRemoteSettings gains a "connections" property, and "connection-added" and "connection-removed" signals (with the former replacing the old "new-connection" signal). This also removes the "connections-loaded" signal, since the connections will now always be loaded (via the initialization of the "connections" property) during init()/init_async(). Also, this removes NMRemoteConnection's "removed" signal, since it's redundant with the new NMRemoteSettings::connection-removed (and having the signal on NMRemoteSettings instead is more consistent with other objects).
