Message:

QtTimeLine no longers queries WorldTime directly.

• This was slightly prone to race conditions when manipulating the slider in the UI while stuff was going on in the background. Instead, we query the QtObservedInstanceBoard.
• QtObservedInstanceBoard has ObservedValue for WorldTime.
• introduces ObservedMaximumAtomTrajectorySize that aggregates the maximum trajectory size over all atoms and provides it as an Observable. We need this value in QtTimeLine only right now.
