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

+;;; prelude.el --- My attempt at augmenting Elisp stdlib -*- lexical-binding: t -*-
+;; Author: William Carroll <wpcarro@gmail.com>
+
+;;; Commentary:
+;; Some of these ideas are scattered across other modules like `fs',
+;; `string-functions', etc.  I'd like to keep everything modular.  I still don't
+;; have an answer for which items belond in `misc'; I don't want that to become
+;; a dumping grounds.  Ideally this file will `require' all other modules and
+;; define just a handful of functions.
