virtual scroll does not work if scrollable area is the document itself

The scroll binding does not work, calculation visible items fails.
I am working on getting it to work properly when scrolling the document. The scrollbar itself jagges a lot when scrolling, though the heights of the individual items is calculated properly. I am still investigating that issue.

The jagging is out of scope of this plugin; fixed that by setting the overflow:hidden trick on the before and after elements. Issue arose cause all scrolled elements has a float:left property (bootstrap).
