Add propogating selection to attribute panel feature
This MR introduces a feature that if user does a selection in model
tree or render view, it would update the attribute panel.Switching tabs
, creating
and copying
new definition would also preserve selection.
qtSelectionManager is also exposed to qtUIManager. A logic error is fixed for qtSelectionManager so that when selected from attribute panel, we would only update selection once.
