GApplication: emit signals on action changes

Browse Source 
Now that we're a GActionMap the story about propagating signals from our
(now-constant) internal action group is vastly simplified.  If someone
calls g_application_set_action_group() then signals will stop working --
but this function is deprecated and they never worked before, so no big
loss there.
