Make scroll follow the cursor

[michael]

This is really needed for a serious editing experience. I will work on a scrollToCursor/Selection implementation and then we connect it with the Surface.

If only this would work for contenteditable too: http://jsfiddle.net/2r2fpekx/12/

One problem is that a collapsed selection does not have a bounding rect.
This describes a hack to get such a rect by injecting a span temporarily: http://ask-wenda.appspot.com/r/5707702298738688/5648640/know-when-caret-goes-outside-of-contenteditable-scrollable-div

When we start to render the selection ourselves we will have everything to get this done.

We can't do that yet, as we need to render selections always for that.

Shifting to Beta 3

While we have the methods now, we still need to integrate it. Shifting to beta 5.
