Subject: Better dune ocamldebug integration

- use coqc instead of coqtop (since -compile doesn't work anymore this
  is better)
- pass through extra arguments to dune-dbg
- auto detect the need to pass -emacs to ocamldebug
- instructions for emacs users

The dune-dbg dependencies are still broken ;_;
