Zoom buttons for Fit All, Home, Center

[naught101]

I accidentally zoomed out way too far (pinch zoom on a touch screen is VERY sensitive), and now I can't find my sketch.

Having some zoom buttons to zoom to the entire drawing, and to zoom to home (original view, 100% zoom) would be very useful.

@naught101 @mbrlabs Do you have a favorite button combination for these zoom options? Or would you use a button in the toolbar for this?

I think I already have a solution for zoom to the entire drawing, and to zoom to home. But I would like to know your opinion about how and where you can use those functions.
