Exporting Meshes Shouldn't Overwrite Files

[AbstractAlex]

When exporting a mesh it will also export textures sometimes.

If you already have a texture with the same name in that directory it will replace the file. Ideally it would add a suffix such as “_1” afterwards. (This also need to be reflected in the mtl file)

I’d kind of like it to make a new folder with everything in it, so that for large exports it’s clear what is part of the export even if the destination directory is a bit cluttered.
