[ESS] Introducing Polymode

[Mathieu Basille]

Dear Vitalie,

It's great to hear from your efforts in Polymode! I just tried to use it on 
Rmd files on Emacs Snapshot [24.3.50.1 (x86_64-pc-linux-gnu, GTK+ Version 
3.4.2) of 2013-03-25] on Debian. First I tried to simply add the following 
to my .emacs:

(setq load-path (append '("/home/mathieu/.emacs-site/polymode/"
       "/home/mathieu/.emacs-site/polymode/modes") load-path))
(require 'poly-R)
(require 'poly-markdown)
(require 'poly-noweb)

As stated in the above code, I downloaded (using git) Polymode in 
/home/mathieu/.emacs-site/polymode/

If I now visit a .Rmd file, I get this after startup:

Error during redisplay: (jit-lock-function 1) signaled (void-variable 
object-name)
Error during redisplay: (jit-lock-function 522) signaled (void-variable 
object-name)

And from time to time if I navigate in the file:

polymode error: Symbol's value as variable is void: object-name

I don't know if this is useful, but Emacs indicates (Markdown Rmd vl Wrap), 
as compared to (Markdown vl Wrap) without Polymode. If I try a polymode 
function (such as M-n C-n), I get this:

equal: Symbol's value as variable is void: object-name
polymode error: Symbol's value as variable is void: object-name

Appart of that, not much happened compared to regular Markdown mode. 
Shouldn't it load R (minor) mode in R code chunks? I also tried to remove 
everything from my .emacs, and use only the few lines above, with the exact 
same result. Am I missing anything here?

Thanks again a lot for your work on this!
Mathieu.
