Title: Graph zooming with Alt Key

As promised, I've enabled graph zooming and panning when the alt key is held down.

Zooming is working well but the panning still needs some work. It is getting disabled after zooming or normal repositioning of the nodes.

I had to bump up the d3 version to get the zoomstart event.
