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.
