+major refactors to vanilla Emacs config

Developed quite a bit of the config.

I've added a literate org config, loaded through the init.el file.
Furthermore, I've added some basic general maps and have gained a much
better understanding of Emacs than before. This refactor is one of the
main reasons I decided to so heavily refactor my doom config.
