[Addon] OpenSCAD import updated for Blender 2.73

Hey, I had to make a number of tweaks to the openscad import script I found ( https://github.com/maqqr/blender-openscad-import/blob/master/importscad.py ) in order for it to work, so I though I would share my changes here.
https://github.com/cubedparadox/blender-openscad-import here is the repaired file.

Edit: my changes were forked, and improved, get it here https://github.com/maqqr/blender-openscad-import

Some things to note:
Scaling feels off, I’m not sure if that’s something I did or not, but parts feel too big.
I also had trouble with windows permissions, openscad needs to be able to create files in the Program Files directory.
Speaking of program files, you need to have openscad installed to use this addon, I have it pointed to C:/Program Files/OpenSCAD by default, you may need to change this in the .py file.
