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

;;; screen-brightness.el --- Control laptop screen brightness -*- lexical-binding: t -*-
;; Author: William Carroll <wpcarro@gmail.com>
;;; Commentary:
;; Mainly just Elisp wrappers around `xbacklight`.
;;; Code:
;; TODO: Define some isomorphisms. E.g. int->string, string->int.
Support prelude/start-process If you refer to the previous commit where I change shell-command usages to start-process function calls, you'll see the rationale for why I prefer start-process. This commit introduces a more ergonomic API for start-process that fits most of my current use-cases of it. This cleans up the code. I have introduced a bug in the way that I'm tokenizing the COMMAND value. I've tracked that with a TODO. For now it only affects the `xmodmap -e '<command-string>'` calls, which isn't too disruptive.
