Handle files without filename extension as txt

[Grecco-O]

I don't know if it's more a bug or a feature request.
If you try to upload a zip with a file which has no filename extension the upload succeeds but if you try to open the model manyfold returns with a 500 error.
In my case it was the License file in the zip of https://www.extrabold.tools/

It's easily user-fixable, just add a .txt at the problematic file.

But maybe letting manyfold flag it as a text file would also be good.
Thingiverse for example doesn't have this problem because they give you the file with the correct extension.

Good point, LICENSE and README are fairly common. I'll look into it.

here is a known problem model https://www.thingiverse.com/thing:6949084

I found this out after resyncing the link -

Grecco confirmed the issue is most likely due to the stl's formatting since its ".001.stl"
