Update: Checking against null and allowing it to be passed through to the original scroll function. If this isn't desirable I can revert it.

Regarding #161: Adding a couple of quick checks wherever the original scroll functions are called to ensure properties on
arguments[0]aren't accessed if its value isnull, aftershouldBailOut(arguments[0])evaluates totrue.
