[wip]Wings2Thea

[nigec]

I've started again with the current version, I over complicated things last time, my goal is just an exporter

Thea can use KT files, so it was quite easy to get it rendering

What does work:
Ambient Occlusion and spherical image
Lights: point lights
materials with textures and normal maps
Camera and settings
export, render, save image and close

First things first:
ability to set a sample limit or time limits.
Options to how Thea runs.
Read the registry to find Thea's data folder
Use external presets rather than the hard coded ones, which don't work.
Tidy up the render preset code

Just those things will make it useful.. then I'll work on getting the physical sky working, that is totally different
Then everything else lol
