* Allow compilation without network manager support, since some

	distros doesn't have it (like Slackware).
	* settings/xfpm-settings.c connect to the signals after settings up all
	the widgets this way we don't get property_changed signals for nothing.
	* Register DBus error code only once at startup to avoid a Metadata
	warning error domain.
	* Update README, NEWS.
