[PATCH] add lowercase c to languages recognized for CSS highlight

[Nikolaos Chatzikonstantinou]

With an org file like this:

#+begin_src c
/* ... */
#+end_src

you get valid recognition by babel, etc, but it is not recognized by
ox-html's CSS file. Of course not all cases can be supported, but I
think that this one is common enough for you to include.

Regards,
Nikolaos Chatzikonstantinou
