Added settings.draggingTimeout.

Useful so that the onClick events know they were dragged. without it the dragging flag is set back to false before the click event fires. E.G.

$overscroll = $('#overscroll').overscroll();
$('#overscroll > a').on('click', function(event) {
event.preventDefault();
dragging = $overscroll.data('overscroll').dragging;
console.log('Dragging: ' + dragging);
if(!dragging) {
console.log('Click');
};
});
