Removed gun kickback

Raised the first person camera a bit, as someone requested (had to change the crosshair too).

Added two new skins: 'Red Baron' and 'Black Falcon'. Note that the skins are not faithful recreations of their real life counterparts and are only cosmetic.

Increased health.

Changed the machine guns' damage types to 'Heavy Arms' so that there is no armor damage reduction from other modded planes. Also modified the team colour materials as requested.
