Add property tree view

The standard tree view widget is not capable of setting individual cell
renderers per row. Thus I made one with a custom cell renderer that uses an
appropriate cell renderer depending of the property type.

I developed this independently and put it up on Github at
https://github.com/matze/EggPropertyTreeView.
