Cannot change style for WFS layers

A lot of WFS layers report themselves back as a generic "Geometry" as such the simple style configurator has a rough go of it; while it lets the user interface edit fill, line, mark, text these things have been modifed to only change the first symbolizer (rather than all of them) as such we are broken.

We need to show the "mode" (point, line, poly) to the user and let them choose what to do when we don't know from the data...
