Axis context menu for toggling X/Y scale and limits

Adds a special context menu to the axis that helps toggling the scale and limits of the axes.

Adds scale (linear / log) and axis limit (auto / manual) toggling as a special contextmenu of the axis (not the regular uicontextmenu of the axes).

toggleAxisContextMenu()
toggleAxisContextMenu(hAxes)

example:
toggleAxisContextMenu(gca);

Important: This function relies on the uiaxiscontextmenu by Lior Cohen.
