Cruiser captains should always be wearing some eye piece. However, Walker didn't have that during mission 3 and 4. This has now been added. Also, there is one moment during mission 11 where Walker can be seen flying a Defender. Here he should be wearing a helmet, but he wasn't. This has been added. This commit also replaces the comm_ge_generic1 (Pirate) helmets with comm_ge_generic2 (Liberty) helmets, and also the uniforms li_scrote_body to li_male_elite_body. The former Pirate helmets and LSF uniforms were incorrect because they were worn by Liberty Navy pilots.
