[8u40] API Review: Allow auto-hiding of PopupWindow on owner node press

[Martin Sladecek]

Hello,
I propose a new property for PopupWindow that would allow developer to 
control autohiding policy when PopupWindow has an owner node. Currently, 
clicking the owner Node does not hide the window, but the new property 
(autoHideOnOwnerNodeMouseEvents) can change this.
