Title: Making markdown engine configurable per slideshow

Sometimes I need to put math on my slides and this was pretty much a showstopper for showoff for me, but then I discovered Marukus math mode (via Jekyll). Since the markdown engine is now selected via tilt, I added a feature that allows choosing the markdown engine per slideshow (with redcarpet as default).

As a result you can write something like this in your showoff.json

```javascript
{
/*other config*/
"markdown" : "maruku",
"maruku" : {
"use_tex" : true
}
}
```

And this will render the math formulas using blahtex as images and put them on your slides.

Documentation + Tests included.
