Add postload folder for automatic end of load order files
This is a feature that I've heard tossed around for a while, and I've been seeing more and more use cases for it. It'd be incredibly helpful for sound replacements, font replacements, and really everything else of that sort. There's been chats of different names than postload
for this feature, but I don't think it's worth holding up the addition of the feature given that aliases can always be added later.
