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

+;;; bytes.el --- Working with byte values -*- lexical-binding: t -*-
+;; Author: William Carroll <wpcarro@gmail.com>
+
+;;; Commentary:
+;; Functions to help with human-readable representations of byte values.
+;;
+;; Usage:
+;; See the test cases for example usage.  Or better yet, I should use a type of
+;; structured documentation that would allow me to expose a view into the test
+;; suite here.  Is this currently possible in Elisp?
+;;
+;; API:
+;; - serialize :: Integer -> String
+;;
+;; Wish list:
+;; - Rounding: e.g. (bytes (* 1024 1.7)) => "2KB"
+
+;;; Code:
+
+;; TODO: Support -ibabyte variants like Gibibyte (GiB).
+
+;; Ranges:
+;;  B: [   0,  1e3)
+;; KB: [ 1e3,  1e6)
+;; MB: [ 1e6,  1e6)
+;; GB: [ 1e9, 1e12)
+;; TB: [1e12, 1e15)
+;; PB: [1e15, 1e18)
+;;
+;; Note: I'm currently not support exabytes because that causes the integer to
+;;  overflow.  I imagine a larger integer type may exist, but for now, I'll
+;;  treat this as a YAGNI.
