This is a major rework on how images are loaded and stored. Unfortunately, this is so entangled that doing each change as an atomic step is pretty much unfeasible. The first major change is that BgSource now returns a GListStore instead of a GtkListStore. This is necessary for us to bind it to GtkFlowBox, and pretty much signals we're not using any of the tree/icon views anymore. Second, the thumbnail factory was moved to BgSource itself. We only create factories for large thumbnails, so it's not needed to handle each one of them individually. At last, switch CcBackgroundChooser to GtkFlowBox, and adjust the signals we connect to.
