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

+;;; list.el --- Functions for working with lists. -*- lexical-binding: t -*-
+;; Author: William Carroll <wpcarro@gmail.com>
+
+;;; Commentary:
+;; Since I prefer having the `list/' namespace, I wrote this module to wrap many
+;; of the functions that are defined in the the global namespace in ELisp.  I
+;; sometimes forget the names of these functions, so it's nice for them to be
+;; organized like this.
+;;
+;; Motivation:
+;; Here are some examples of function names that I cannot tolerate:
+;; - `car': Return the first element (i.e. "head") of a linked list
+;; - `cdr': Return the tail of a linked list
+
+;; As are most APIs for standard libraries that I write, this is heavily
+;; influenced by Elixir's standard library.
+;;
+;; Elixir's List library:
+;; - ++/2
+;; - --/2
+;; - hd/1
+;; - tl/1
+;; - in/2
+;; - length/1
+;;
+;; Similar libraries:
+;; - dash.el: Functional library that mimmicks Clojure.  It is consumed herein.
+;; - list-utils.el: Utility library that covers things that dash.el may not
+;;   cover.
+;;   stream.el: Elisp implementation of streams, "implemented as delayed
+;;   evaluation of cons cells."
+
+;; TODO: Consider naming this file linked-list.el.
+
+;; TODO: Support module-like macro that auto-namespaces functions.
+
+;; TODO: Consider wrapping most data structures like linked-lists,
+;; associative-lists, etc in a `cl-defstruct', so that the dispatching by type
+;; can be nominal instead of duck-typing.  I'm not sure if this is a good idea
+;; or not.  If I do this, I should provide isomorphisms to map between idiomatic
+;; ways of working with Elisp data structures and my wrapped variants.
+
+;; TODO: Are function aliases/synonyms even a good idea?  Or do they just
+;; bloat the API unnecessarily?
