V7.4

* Toned down the AI a bit, but made it more offensive and less defensive.
* Increased the rate of fire on arm starfighters by .3 seconds.
* Doubled the power of the command cruiser's fusion gun.
* Slightly reduced the range on all weapons (mostly by 100).
* Longbow combed the scripts and removed a lot of little bugs. I think we got them all this time folks!
* Longbow added cool fighter death scripts.
* More stability and faster engine speed due to less load.
