BUG: Fixed issue related to Selection Manager and qtModelItem
The problem was that by default every time a qtModelItem was displayed it would update itself based on the curent selection. While this behavior is correct for Operators it is not correct for defining a Simulation.
A mode has been added to qtViews, qtItems and qtAttribute to indicate if this behavior is desirable - note that the class can still choose to ignore this option and use the older manual mode - for example if an attrbute had two model enity items that shared the same selection masks
