Remove everything and restart blank
This commit removes all files currently present in the repo, to prepare for a start from a nothing. This is done due to my recent migration from X11 to Wayland, which has rendered most of these config files no longer releveant. I've currently been tracking my dotfiles in a separate repository, in hopes to get it to a state where it would be mergable here, but that turned out to be much more difficult than I anticipated, and I think it will be much easier to simply move over the history from this temporary repository I've been using onto this one. That however requires a start from a clean point, which this commit creates.
