Added a bool spawnAtTarget to spawn attack in which you can define whether the unit spawns at the target or at the attacker.
In Addition i changed the command which is given to the spawned unit to an attack command on the target cell.
( I think this makes way more sense than giving a move command to the meeting point)
( This also works if the spawned does not have a attack command. It will move to the enemy then)
Added the ability for SpawnAttacks to let the units spawn when the projectile arrives at the targetpos.
Unit will always try to attack if it has an attack command.
Unit attacks the target POS and not the target UNIT of the attacker.
