Record and replay doubleClick for ItemView widgets.
Some non-editable widgets need the doubleClick event instead.
Tested with Paraview test CategoricalAutomaticAnnotations.xml, and adding the doubleClick
event before the edit
event doesn't change the test.
With the CMB widget that uses a tree item view that is non-editable, the edit
event fails, but the doubleClick
event triggers the gui
correctly.
@utkarsh.ayachit @cory.quammen please take a look?
