zoom / pan / rotate / datacursor hotkeys for a figure

MAIN FEATURES:
* Allows to toggle zoom / pan / rotate / datacursor
* Adds "zoom with mousewheel" to "pan" mode
* Said functionality does not disappear when corresponding buttons are clicked on the figure toolbar
(in contrast with a naive approach)
* Provides an example of a workaround on how to fix 'KeyPressFcn' beeing overwritten when cursor mode changes

HOTKEYS:
* 'z' - toogles zoom mode ( last used of zoom-in and zoom-out - assumes
that mouse wheel is used to change the zoom level )

* 'x' - toggles pan mode. Also adds zooming-with-mouse-wheel.

* 'c' - toggles rotation mode

* 'v' - toggles datacursor mode

QUICKSTART:
Try the demo:
>> figkeys.demo_imshow()

or try it on your own figure like this:
>> imshow('peppers.png'); figkeys.setHotkeys();
