 Again this patch does to things:

 1) Add an apply button if the snapping options are in non-docking mode (as
 requested by timlinux)

 2) resolves a problem with layers that are not shown in the canvas: So we
 don't rely on the canvas but on the mapLayerRegistry. Also needed a new
 signal, as the layerWillBeRemoved signal fires to early.
