Add an option to just swipe without crossing the threshold

It would be nice if you could just transition to the next page with a fast swipe by doing something like

if (Math.abs(oldEvent.dx - newEvent.dx) > someNumber){
    goToNextPage();
}

@TheSeamau5 I could take a look at velocity-based switching. Do you have some specific breaking changes in mind for v0.3?

[TheSeamau5]

Yeah, but don't worry. I'll just do the necessary merging. The big one to consider is the support for right-to-left. Basically, you would add an attribute called rtl : Bool which would mean that pages appear in sequence from right to left as opposed to the current left to right. So, to swipe to the next page would mean swiping from left to right. This is just an if-statement, so, as I said, don't worry too much.
