Move everything that is desirable independent of the WM or shell into
xinitrc.
Move .Xresources and .Xmodmap into .config/X11.
Remove all unneeded GNOME bits from i3 config.
Make compositor launch script portable.
Add locker symlink and launch.sh similar to the compositor.
Add blur using the fork from https://github.com/tryone144/compton.
picom seems to be very CPU heavy on my system, so until I figure out how
to fix that I will use this outdated version.
Make the dotfiles a bit more flexible by creating symlinks for stuff
like the wallpaper or the compositor. When switching/exchanging these
components only the symlinks have to be updated.
