placesview: show Computer item

GtkPlacesView widget manages persistent locations,
factoring out GtkPlacesSidebar functionality.

It, however, does not completely shows all sidebar
locations, since Computer is still missing.

Add a Computer item, adjusting some internal behavior
to make that possible.
