Overhaul how the config file works

[EnnuiL]

I have to admit: the config library that Ok Zoomer uses is a bit bloated thanks to the TOML library! Hissboom does a great job at shrinking it to a much reasonable size, but we can still shrink it further! You can either write a better TOML library or you could just switch formats!

Yeah.. I'm likely switching to another format, but one that has gone through the test of time pretty well; I already began progress on it, but since it will require Quilt cooperation? This (and #116) may comprise the part 2 of The Big Update™ if all goes well
