scrolling is jittery on latest iOS

[AndrewBrough]

When using the basic ScrollLocky component, it works as intended but the scrolling behaviour is strange. I can scroll for maybe 100px before it locks. I have to lift my finger and scroll again to make any significant scroll progress down the page.

You have to use -webkit-overflow-scrolling:touch on the scrollable div to fix it, but please be very accurate with it, and test the result - it's breaking layouts including z-indexes and position:fixed

Relax, working almost in 99% cases.
