* Fixed viewdistance error while controlling UAV.
When you take control of UAV drones, the view distance does not properly update to your setting because it thinks that you are still the land infantry guy. So I've experimented a bit in the editor and found a condition that will properly return true when you are in control of a drone aircraft. I've also adapted this for use with land-based UAV stuff (like the Stomper).
To accomplish this, I created a private *_isControllingDrone* variable that will detect if the player is currently in control of any UAV. I also edited the _landVehicle and _airVehicle scripts so if and only *_isControllingDrone* returns true, then it will check whether the drone is a subclass of "LandVehicle" or an "Air".
That's all I did. Please accept my pull request!
