[PATCH] libnm-glib: added "connections-fetched" signal o NMRemoteSettings

[Witold Sowa <witold sowa gmail com>]

A "connections-fetched" signal is emited when the last connection's
settings are obtained or if there was no connections to fetch. The 
signal will inform the user, that the connections list is filled up.
