Elite: Dangerous Python

This is a cleaned version of the Python's gameasset.

What has been done:
- holes are patched, internal geometry has been mostly fixed
- Some things like vents are simplified
- engine-nozzles are separated
- vent-covers are temp atm, will redo them

It should be good enough to get a decent slicing.

There 2 versions available:
1. full model
2. front & back separated

Have fun!
