Change to use a LinkedHashMap instead of a HashMap in the
FlightConfigurableParameterSet. This ensures that the ordering is
consistent with the way the user added the flight configurations.
This will also be true for when reading the flight configurations from
a file. Additionally, to preserve the ordering, do not sort the
FlightConfigurationIds in getIds().
Fixes#845
