[ESS] Making M-n r (for ess-swv-knit) available in polymode

Hey Josh,

I use the following keyboard setup for polymode:

;; F5 to weave / C-F5 to compile to HTML / C-S-F5 to tangle
(define-key polymode-mode-map [(f5)] 'ess-swv-weave)
(define-key polymode-mode-map [(control f5)] 'ess-swv-pandoc)
(define-key polymode-mode-map [(control shift f5)] 'ess-swv-tangle)

With the home-made 'ess-swv-pandoc' function below:

;; Function ess-swv-pandoc to use knitr::pandoc with options in
;; .emacs.d/config.pandoc
(defun ess-swv-pandoc ()
   "Run Pandoc on the associated .md file."
   (let* ((rmd-buf (current-buffer)))
       (let* ((sprocess (ess-get-process ess-current-process-name))
              (sbuffer (process-buffer sprocess))
              (md-filename (file-name-sans-extension (buffer-file-name)))
              (buf-coding (symbol-name buffer-file-coding-system))
	      (format "require(knitr); pandoc(\"%s.md\", format =
	      \"html\", config =
	(message "Running pandoc on %s.md" md-filename)
         (ess-execute pandoc-cmd 'buffer nil nil)
         (switch-to-buffer rmd-buf)
         (ess-show-buffer (buffer-name sbuffer) nil)))))

Of course, you'd have to adjust it to your own setup (and keyboard 
preferences, e.g. M-n r instead), but it might get you started.
