Dynamic application start time

[PavelBal]

For application and events that are repeated, it should be possible to apply the same application/event multiple times. For this, create new parameters:

• Start time
• End time (if NaN -> End time set to simulation time, default is NaN)
• Time between administrations (default NaN) -> Only one event is created

-> Event condition formula is created when simulation is started, NOT when it is created.

-> Parameters cannot be varied (will not work with all workflows relying on SimulationBatch)
