- Display the right docstring for ply files
- Add a filter to *.stl on importing stl files

New: search box.

sort materials so we get predictable output from blender, also add option not to include dates in files.

Lower Delay will rise errors when rendering big images. 
My system Win7 64 (slow HD) reports following error on lower Delay: 
---
Reached EOF while decoding PNG
Cannot open input file
Cannot create backend data
Unknown fileformat
---

Maybe Delay should be bound to the imagesize. Or is there a better solution to wait for povray to finish the writing?

Thanks Campbell

Removed (commented out) Baking from the interface until we work on it again. More important issues need to be solved first.
