Update all submodules to the newest commit.
Change submodule names in `.gitmodules` from local path to repo names.
Sort and group `.gitmodules` by program that uses it.
Remove the clone of 'fzf-tab' as my pull request got merged.
LaTeX files can now be automatically compiled in vim and jumping into
the relevant lines from PDF to code or the other way around is possible
too.
Add the LaTeX coc-language server as well.
Thanks to @AurelWeinhold
These plugins add functionality to automatically close and surround text
with parantheses, brackets, quotes, etc.
Overwrite the vim-surround default bindings since they conflict with my
substitute bindings.
Since the vim plugins are stored in submodules and vim-plug is not a big
fan of that when installing (Needs PlugClean and PlugInstall again
although the repos of the plugins were already pulled) it makes more
sense to me to use vim8s native plugin management.
