In case a file is moved to another location this change will most likely
end in a dangling link in the home-dir. This change fixes this by
removing links automatically which are off because the target-file has
been moved to another location.
I finally made the switch from the bare-repository method to stow to
manage my dotfiles. This brings some nice benefits, e.g. I can savely
say what file is in my dotfiles and what is missing out. Furthermore the
usage is _way_ simpler the before. Though one downside is the more
complicated removal of files, but I've documented a way which feels nice
to me as well. Finally I removed my old setup-script since I switched to
an ansible-setup anyway. So this config will eventually be applied
ansible and I don't have to care about installed software in this repo
anymore!
