Added event.preventDefault to lastclick and firstclick

[matias-sandell]

Using event.preventDefault on the remaining clicks of the firstclick event and all lastclick events since there's no point in allowing default actions on them.

If I for example use the firstclick handler to to prevent multiple ajax requests I would have a event.preventDefault in it. But it would only be executed for the firstclick event, not the remaining click events.

Of course it could be solved by using something like this.

$el.on("firstclick click", function (e) {
    e.preventDefault();
    if (e.type == "firstclick") {
        // Do stuff
    }
);

But that doesn't seem like the right way to do it.
