SimulationTimeCondition - greaterOrEqual leads to crash (no opSimulation.log) & docu wording

Using rules for SimulationTimeCondition other than greaterThan is currently not supported. This should be logged as an error instead of a openSimulation.exe crash .

Furthermore, the documentation says that SimulationTimeCondition defines when a simulation ends. But it can be used as condition for any scenario element. Proposal: remove first sentence.
