Minimal editor

[paoloambrosio]

Fred has requested the following fields in the Chassis (*.cdfbin) to help him tune vehicles quickly:

Name	Hex code	Type
Mass	21 67 0B 57 AB	Int32
BodyDragBase	24 33 63 ED FD 21	Float32
GeneralTorqueMult	22 A3 BF 1E 60	Float32
GeneralPowerMult	22 C3 66 7D 2E	Float32
MaxForceAtSteeringRack	21 01 C1 8B 82	Int32
PneumaticTrail	22 3E 53 B5 CF	Float32
PneumaticTrailGripFractPower	22 00 AB 3E 9B	Float32

Requirements:

• Open the *.cdfbin file directly (later we'll open the *.crd file, that represents an entire vehicle, and find all other files from that one)
• Display the values read for each property (hardcoded for now, see Generic field editor #5)
  • Not present becomes null in model and empty string in view
• Edit the values
  • Validation to make sure that it can be converted to the correct type
• On save, overwrite the already configured values (later we'll create the file completely, see Generic fbin editor #4)
  • Error if they are null but present in file, or if it can't find them and they are configured
