Shuttle atmos-to-atmos fixes + correctly coloured windows for some ships

[hazelrat]

• Set cycle_to_external_air to true for every shuttle I could find that lacked it, in code if they were already defined in code, and in the .dmm otherwise. This means they should cycle air to air correctly, previously they were not actually making use of their out vents.
• Adds coloured windows to the Idris, IAC, Sadar, and Hephaestus Security offships where missing.
