RCS mesh not recieving shader

[Bufflak]

Internal logic seems to be:

• FASA_Stock uses a flat mesh that's part of CM model, thrusters come from CM texture
• FASA_RO switches this to a proper model (or maybe just adds it ontop?)

solutions:

• just make stock use RO model, looks much better
• separate cfg for stock and RO

Fixed by using RO model.
