Model file name restriction

[eknim]

It is inconvenient to rename model file's name to "scene" to upload.
In usual case it can be assumed that one zip file have only one model.
So if the model file is discerned by it's extention the file name restrictions can be eased.

Current upload rule allows fbx, ply, gltf, glb file with any name, but .usdz file name should be named as 'scene.usdz'.
For convience and consistancy, your suggestion is better way to upload model files.

I'll apply this on the next release.
