Streamline the meme-exposing method definition as Rubinius bytecode
Change quest syntax to '.?' to make room for Ruby 'method!' and 'method?'
(which aren't going away as long as we want to be able to share
 objects back and forth with Ruby)
Change declobj separator to arg_sep (',' instead of ';')

This makes room for multi-expression meme declarations without curly braces
  Object { foo:x=8;x+5, bar:8, baz:99;100 }
