Title: Double Click to zoom

A feature that I really love on touch devices and generally find quite usable. This PR implements a "double-click" zoom feature, which will zoom (by 20%) and center at the point which were double clicked. I'm not sure what you'll think about this, and one little regression is that it's now impossible to double click at text for selecting it, without zooming.

Let me here what you think, and please share any thoughts for improvement.
