Change the default code highlighting ?

[FrancescoFilippi]

Is it possible to change the default code highlighting and use, let's say, something like the github markdown (light grey box included)?
E.g.

mood = 'happy'
if mood == 'happy':
    print("I am a happy robot")

I think this may have been implemented by @tobiasbueschel in #36. The pull request has been sitting around for an embarrassingly long time, so I'll take a look in the next day or two.

Thanks go to @tobiasbueschel for this

(Tobias, I didn't directly merge because git complained: "Patch is empty. Was it split wrong?", so sorry the commits aren't in your name. )

Looks really good!
I'll definitely try to add another custom language syntax highlighting. Maybe open a pull request if I'll succeed.
