We only allow overflow scrolling. The frame isn't special. This is a first step in making that happen. There's a lot of code to remove after this patch, but this gets rid of ScrollView and a bunch of frame-level scrolling code. Had to add in a FrameWidget class so that Scrollbar.cpp had a way of getting to FrameView::removeChild without pulling a core class into platform. This might go away when we rip out the Widget tree if we made it so that FrameView didn't keep a list of Scrollbar instances. Modified scrollbar.html to use overflow scrolling instead of frame level scrolling. Once we get rid of the split between Document and documentElement, we'll be able to make the root element in the page scrollable as well (i.e. any child of the Document).
