Currently ProjectileCreated and co are called for all projectiles created on the map (in synced code, for unsynced it does an ally owner check). This spams a HELL LOT of lua callins, making the usage of this events extremely slow (imagine all those EMG weapons on Flashes). So to speed it up it needs a callout function to limit the events to wanted projectiles (as it is done with the Explosion callin already, see Spring.SetWatchWeapon).
Also it needs something like Spring.GetProjectilesInBox(x1,z1,x2,z2).
