Move utils back into dotfiles repo #4
Description
Ever since I split this repo from the dotfiles repo, I can't think of a single case where I've actually used one without the other, so keeping these two separate is a bit silly.
The original idea was to split utility tools from pure configuration; but that separation line is rather blurred (see e.g. $XDG_LIB_HOME/tmux/tmux-view, or just all the wrapper scripts), so it feels a bit arbitrary.
And since our goal is to eventually move out everything in here to their right place anyway (see #3), mashing up executables with configuration will only be temporarily be an issue.
This will simplify the dotfiles setup, as we no longer have to handle a case where the utils repo is potentially missing. Missing condition checks for the PATH envvar setup then gets us closer to doing everything in environment.d (see ayekat/localdir#32).
