[Bugfix] Restored AUTOMATIC Ignition Event, et al.

Restored Automatic ignition Option
    - "bottom" core stage is the lowest centerline ('AFTER')
    - Parallel Stages are always considered as 'launch' stages...
      and thus ignite on launch.
Motors now copy Ignition parameters when loaded into a rocket.
Added additional error checking in FlightConfigurationID
    - class is now tolerant of random string initializations
