X-15 fuselage Vector3 error

Was getting an improper format error for bluedog_X15_Fuselage and was able to fix it with this patch:

```
@PART[bluedog_X15_Fuselage]:FINAL
{
    @EFFECTS
    {
        @jettison
        {
            @MODEL_MULTI_PARTICLE 
            {
                @localRotation = 1,0,0
            }
        }
    }
}
```
The original value was a Vector4 of `localRotation = 1,0,0,-180`
