Massive configuration overhaul

Currently paying the price of months of non-diligent git usage.

Here's what has changed.

- Theming support in Gvcci and wpgtk
- Dropping support for i3
- Supporting EXWM
- Many Elisp modules
- Collapsed redundant directories in ./configs

+;;; colorscheme.el --- Syntax highlight and friends -*- lexical-binding: t -*-
+;; Author: William Carroll <wpcarro@gmail.com>
+
+;;; Commentary:
+;;
+;; TODO: Clarify this.
+;; Since I have my own definition of "theme", which couples wallpaper, font,
+;; with Emacs's traditional notion of the word "theme", I'm choosing to use
+;; "colorscheme" to refer to *just* the notion of syntax highlight etc.
