[MLton] Emacs mode for editing ML Basis files

Cool!

FYI, Ray Racine submitted an MLB-mode (mlb.el) last year.  It was
pre-wiki, so it didn't make it up there.  Anyways, I added that to the
wiki for comparison.

I fixed it (behind the scenes).


When I try it, I get the following error (repeatedly).

(4) (warning/warning) Error caught in `font-lock-pre-idle-hook': (error No such face font-lock-module-def-face)

Also, it seems to have trouble indenting after the following line

basis B = bas end
