adaptive class names for level of zooming

If we're taking over scrolling, we should think about map nav ux. Drag graph to scroll. Zoom widget.

Also, should use css translate to let the browser accelerate scrolling (the current overflow:hidden scrolling isn't accelerated).

@forresto there is certainly lots of performance optimization work there that can be done. But first, let us have everything working with #28 reliably :-)

Another interesting side-effect of zoom control on JS level is that we could modify the UI itself by zoom level, for example by hiding/showing details of nodes based on how far out or in you're zoomed.
