Fixed part of artillery pickup exploit

Browse Source 
- Current behaviour is that when destroyers/defenders are created their target position is set to the entity that killed them.
- If a player picks up the artillery after the capsules spawn then they lose their cause.target and stop, not reaching the cause of the turret death.
- I've changed this behaviour so that if the target.cause is artillery then it spawns a defender/destroyer projectile NOT an entity. The projectile target can therefore be a position not an entity. So the capsules won't stop if the artillery is picked up.
- If the cause is not artillery turret or wagon then a destroyer/defender capsule entity is spawned instead of a projectile because a projectile cannot track the player.
- If the player picks up the artillery turret before the projectile that kills a turret arrives then the event cause.name will be missing and no bots spawn at all. I have changed the behaviour so that "if not cause" then we assume they're doing something fucky. We won't have the entity cause name or position, so let's just spawn double the normal amount of destroyers and just send them at 0, 0 since we know nothing else to do with them.
