Evacuate.cfg requires evacuation to be via a single vessel

[Cooper42]

The 'Evacuation' contract can only be completed if the evacuation vessel can hold all the crew at the same time.

For example: Two or more ships already docked to a station which, together, have enough capacity for all the station crew. However, if none of them are large enough to hold all the crew at the same time, the contract can only be completed by sending a new ship that has a large enough capacity.

I did try a few edits to Evacuate.cfg using ITERATE to work through @/StationCrew, assuming that might be a solve, but I couldn't get it to produce multiple, individual VesselParameterGroup parameter types for each crew member.

Another issue to the evacuation mission: If you have 2 evacuate missions at the same time for different stations, one of both will fail!
