Carlos Soriano 89a34210cb gtkplacesview: improve networks feedback 
Add a spinner when networks are being fetched and make
the network section permanent and show a placeholder with
a message that no networks were found in case there are no
networks. In this way users from previous versions won't be
confused with the fact that no networks are shown.

/**
* SECTION:gtkplacesview
* @Short_description: Widget that displays persistent drives and manages mounted networks
* @Title: GtkPlacesView
* @See_also: #GtkFileChooser
*
* #GtkPlacesView is a stock widget that displays a list of persistent drives
* such as harddisk partitions and networks. #GtkPlacesView does not monitor
* removable devices.
*
* The places view displays drives and networks, and will automatically mount
* them when the user activates. Network addresses are stored even if they fail
* to connect. When the connection is successful, the connected network is
* shown at the network list.
*
* To make use of the places view, an application at least needs to connect
* to the #GtkPlacesView::open-location signal. This is emitted when the user
* selects a location to open in the view.
