Icon fonts not loading on linux

[alliumm]

A lot of icons are using the wrong font glyphs on linux. I assume that means some of the fonts aren't loading correctly.
Also, the hud folder name must be all-lowercase for it to load on linux.

I see that the text font is in otf format and the icon fonts are ttf, maybe that's related?

It's actually just the filename capitalization
