Cannot zoom graph without scrollwheel

[ljantzen]

I usually work without an external mouse pointer, and use the pointer 'rubber' on the keyboard to generate mouse movements. This means I have no scroll wheel at my disposal. So zooming in and out of the graph view is really not possible, unless there are some undocumented keyboard shortcuts available.

I would really like some 'zoom in', 'zoom out' ,'reset zoom' and 'fit all nodes in view' buttons in the graph view.

Good point indeed.

Added fit all button. It will be available in 2.2.x. Next buttons will follow shortly
