Title: Mouse scroll handling 

I devised a simple algorithm that goes to the next slide despite the required direction. Slides can be switched easily with mouse scroll, which is much more handy than trying to click the navigation arrows. I am a wireless mouse user ;)

Also - scroll event is throttled to prevent problems with carefully scrolling just a single slide.

This is on by default, you could make it optional quite easily.
