Title: Fixed issue #41: Scroll inside draggable elements contents doesn't work on iPad

The reason scrolling wasn't working was because simulateMouseEvent was always calling preventDefault on the original touch event. This version instead calls preventDefault on the touch event only if the widget calls preventDefault on the simulated mouse event. This allows scrolling and dragging to both work on the same element. Tested with Sortable, Draggable, and Resizable.
