Obj2egg Update and Fork

Hello everyone,
I’m working on a computer science project and required the use of something to get models out of Blender 2.8 (and other programs like Autodesk Inventor) for use with Panda3D. As Yabee is currently unavailable for Blender 2.8 I set about updating Treeform’s obj2egg script.

I believe it works with the latest Panda3D and is designed to work with Python 3. Please let me know if you come across any bugs.
