This commit adds the komorebi-gui debug tool build with egui and eframe.
This tool was built from scratch in a YouTube mini-series which can be
found here: https://www.youtube.com/watch?v=zZKjBMt4kZ4
The most interesting part of this tool right now is the ability to view
debug information about each window as it goes through the rules engine.
While it's possible to change runtime configuration options with this
tool, it is not yet possible to write those changes out to the
configuration file.
