Motors are now cloned for each new simulation (including background and foreground runs)
-> motors are now cloned within the configuration clone method.
-> MotorInstance.reset() resets instance to launch state
Removed spurious negative time-step check in ThrustCurveMotorInstance:154
-> was triggered during normal simulation operations.
Added MotorInstance time updates to AbstractSimulationStepper:
-> moved from MotorInstanceConfiguration.step(...)
Misc variable name changes to be more descriptive
