Title: R-mode: Support prettify-symbols-mode.

Prettify-symbols-mode is new in the upcoming Emacs release. It can
convert symbols into unicode representation, e.g., <- to ←. This patch
sets the `prettify-symbols-alist'. The user can then activate the
prettify mode by calling `prettify-symbols-mode'.

* lisp/ess-r-d.el (R-mode--prettify-symbols-alist): New constant.
(R-mode): Set `prettify-symbols-alist'.
