wip: refactor: Break init.el into modules

Currently, we will just throw everything into modules/ and require it.  As the
Emacs config grows in complexity, we can make the minor improvement to require
everything under glob modules/*.el without explicitly naming each feature.
Further, one could easily imagine a module system with conditionals and flags à
la Doom.
