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 cycling through display configurations Today when I opened my laptop, I wasn't sure if it was powered off or on because the display was blank. Thankfully the volume was muted and the LED indicator was on, which informed me that the laptop was powered on. This saved me from unnecessarily rebooting. What happened was that last night I was working from home and using my external monitor. Usually I enable my external display and disable my laptop display. But when I left for work this morning, I unplugged the HDMI cable from my laptop without disabling the external display or enabling the laptop display. I noticed a XF86 button on my laptop entitled XF86Display. I figured that this could be a nice place to bind a key to toggle my laptop display on or off. At the last minute, I had the idea to just cycle through all possible display configurations that I use; there are only three anyways. When dealing with more than two states, I realized I should use a cycle to model the configuration states. Now I'm thinking that I should be using cycles to model toggles as well - instead of just using a top-level variable that I `setq` over. I haven't refactored existing toggles to be cycles, but I am excited about this new keybinding. This commit additionally: - Moves keybindings out of display.el and into keybindings.el - Conditionally sets KBDs if using work laptop

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.

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.
