- Add -unicode flag to coqtop (sets Flags.unicode_syntax). Used to

  change the default pretty-printing to use Π, λ instead of
  forall and fun (and allow "," as well as "=>" for "fun" to be more
  consistent with the standard forall and exists syntax). Parsing allows
  theses new forms too, even if not in -unicode, and does not make Π or
  λ keywords. As usual, criticism and suggestions are welcome :)
  Not sure what to do about "->"/"→" ?
- [setoid_replace by] now uses tactic3() to get the right parsing level
  for tactics. 
- Type class [Instance] names are now mandatory.
- Document [rewrite at/by] and fix parsing of occs to support their
  combination.
- Backtrack on [Enriching] modifier, now used exclusively in the 
  implementation of implicit arguments.
