[ESS] Parenthesis highlighting in ESS 13.09

[Vitalie Spinu]

Hi Mark, 

It is not very clear what do you mean by highlighting. ESS doesn't
highlight parenthesis and never did. There is parenthesis matching in
core emacs (see variable blink-matching-paren and (elisp) Blinking) and
there are several libraries to highlight parenthesis. Good choice IMO is
rainbow-delimiters, also available from MELPA.
