AircraftReservation with FlightTypes

[pschuler78]

The server implements new AircraftReservations including FlightTypes. The major changes are:

• Server returns AircraftReservationTypes including FlightTypes
• AircraftReservationTypeListItem have now more properties (IsObserverPilotOrInstructorRequired, IsPassengerRequired) for logic control like in flight editor form and uses Guid for ID.
• AircraftReservationDetails changed property name "InstructorPersonId" to "SecondCrewPersonId"

The new implementation is in branch: dev-FlightTypeReservations

Tasks todo on client:

• Change property names in AircraftReservationDetails, AircraftReservationOverview and SearchFilter
• Implement logic for displaying/hidding SecondCrewPersonId combo box like:
• Display "Instructor" for SecondCrew selection when IsInstructorRequired is true (even 1 seat glider selected). Make it mandatory.
• Display "Überwacher" for SecondCrew selection if IsObserverPilotOrInstructorRequired is true (even 1 seat glider selected). Make it mandatory.
• Display "Passagier" for SecondCrew selection if IsPassengerRequired is true (even 1 seat glider selected). Make it mandatory.
• Display "2. Flugbesatzung" for any other AircraftReservationTypes if 2 seat glider or multi-seat aircraft is selected. Make it optional.
