Make folder paths case insensitive.

In Microsoft Windows, files aren't case sensitive. I feel like we should maybe replicate this in folder paths.

This is the current capitalization, it works. But if someone perhaps types something like...
https://winbin.wtf/windows/system32/taskmgr.exe/
Suddenly it breaks. This doesn't reflect Windows behavior, and can be a hassle for some people. Either way, this is really low priority, just thought about it.

Not sure how easy that will be to do with Jekyll/GitHub Pages. Definitely a valid point and something to think about though.

Updating this issue for myself to remember later why this was re-opened. The PR that was merged works when running Jekyll locally, but for some reason it doesn't work when published with GitHub Pages.

Ah, haha, yep!

I did some initial digging into this, and it appears that GitHub Pages' web server is deliberately causing this issue. I'll do some more testing, but we may not be able to fix this without self-hosting the jekyll site.
