Single Mission Beta — Helicopter Gunship DEX Steam update #5772534

This update adds the following...Final part of the missile optimisations. All rigidbodies have been removed from the missiles and replaced with light weight movement calculations. There may be some differences in the maneuverability and speed (mostly positive ːsteamhappyː). There is now far less slow down when the missiles start flying ːsteamsunnyːFixed a bug in the TSD targeting system which was not picking up the distance to the target. This mostly had no impact except when using Hydra rockets which prevented their pod from being able to gimbal up & down correctly. This only effected targeting using the TSD, using the targeting pod itself was fine.
