Support for more modern mesh format(s)

[jujubeja]

• glTF (Khronos standard, alive)
• COLLADA (Khronos standard, old)
• M3D

I personally recommend glTF

For now I would like to keep dependencies low and I think a simple, human-readable format such as obj #290 is perfect.

That being said it might make sense to consider other formats in the future.

obj is supported. I don't think it makes sense to support any other, more complicated formats, unless an artist working on the game or a popular addon asks for it, which you don't seem to be.
