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

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.

Support keybindings for using 4k monitor I'm not sure I'm sold on the "D{0,1}" keybindings. The thought was that 0 would indicate off and 1 would indicate on. This seems sensible to me. I'm hesitant because I don't think I have precedent for this idiom in any of my existing keybindings. I'm also not sure I like these being leader-prefixed keybindings.

Debug xrandr integration to support 4k monitor Two things: 1. I'm unsure if what I previously committed ever worked because the arguments to `string/format` were flipped. 2. I'm unsure why my screen devices are sometimes eDP-1 and eDP1. Perhaps expect more commits as this becomes more clear to me.

Track TODO for investigating 4k monitor scaling It seems like something when I run `display/enable-4k` my resolution isn't at 4k fully. However, when I call the same command on the command line it does scale properly. This doesn't sound likely, and frankly I haven't had too much time to try and reproduce this. Hence - the TODO!

Attempt to debug xrandr behavior in display.el Currently, after I connect my monitor to my laptop, I run `display/enable-4k`, which will use `xrandr` to enable the display. The scaling of the enabled display is not what I expect. So I've habituated re-running the same function, `display/enable-4k`, which scales the display and meets my expectations. What's strange is that if instead of running `display/enable-4k` the first time from Emacs, I call `xrandr ...` from a terminal, this enables the display and scales it properly on the first invocation. I'm unsure how to explain this behavior. It's possible that a environment variable is set properly in the terminal that isn't set in my Emacs, but this is just a guess. I'm going to using a different invocation in display.el that explicitly passes the monitors dimensions. Let's see if that works.
