Use icon overlays for the editable and overview status of a layer
instead of separate icons in separate columns. Still only applies to
the actual layer file entry in the legend, but removes the need for
the extra columns. However, I'm hopeless at icon drawing...
These changes are a variation on the suggestions in ticket #191.
