Update our parse errors to match latest illuaminate

We've been out-of-date for a while now, as we needed to update
lua_menhir to work with lrgrep 3.

 - Better handling of standalone names/expressions - we now correctly
   handle lists of names.

 - Handle missing commas in tables in a few more places.
