New features implemented:

• fitImage: size an image such that it takes up the remaining space of a slide.
• slideAutoAnimate: alias for slide(slideOptions(autoAnimate=true))
• disableVerticalCentering: disables Reveal's vertical centering of all slides.
• You can now use fadeIn in combination with other fragments!

Now all the tutorials are written. It's just some cleaning and summing up that's left.

And I have finally figured out how to get fadeIn in to behave as all the other fragments! :partying_face: Now you can mix it with the others like you'd expect:

fragment(@[fadeIn, grows]):
  nbText: "Fade in and grow at the same time"

Previously, it would ignore the fadeIn and only grow. But now it works!
