Since fzf is not really only a zsh plugin this moves it to .local/bin.
I am not quite sure it will stay there.
The submodule was also updated in this process.
Update all links and references.
Add .local/share directory that contains the man pages. By that dotbot
just globs all of them and symlinks them. This makes it more modular and
a bit more transparent on how an installed system looks like, just by
looking through the repo structure.
