Fix ViewBox axis zoom in RectMode and examples/customPlot.py (#1443)

Browse Source 
* Fix examples/customPlot.py: mouseDragEvent misses axis argument

Fixes #1277

* customPlot.py: Update methodolgy to disable menu

If there's an argument for this, we should use it

* customPlot.py: Show how to disable axis interaction

* Fix ViewBox: Moving axis in RectMode not implemented => use normal move mode

Grabbing an axis in RectMode leads to the zoom rectangle being displayed
in unreasonable positions. In this case, fall back to normal mode.

* customPlot.py: Only disable right-click zoom for demonstration

In cases where continuous zooming is not wished (e.g. in case of
complicated rebinning after zooming), this might come in handy
and there is no reason not to show it.
