[ESS] Introducing Polymode

Dear Vitalie,

This seems to work beautifully! I already love it, especially for .Rmd 
files. Polymode, adopted!

I still have a few error messages, which do not seem to translate into real 
effects. Right after opening a .Rmd file:

Error during redisplay: (jit-lock-function 1) signaled (wrong-type-argument 
stringp nil)
Error during redisplay: (jit-lock-function 522) signaled 
(wrong-type-argument stringp nil)

And from time to time (but I can't seem to find the pattern when it 
occurs), I have the same error message, but for functions 110, 682, 1042, 
1201, 1561, 1720, 2591...

I really don't know if this is problematic, since I can't see any troubles 
with it...

Thanks a lot for your work, it is so good to be able to use Emacs properly 
on .Rmd files!
Mathieu.
