TowerMissiles faster, fire more efficiently 

Missile optimized to fire a 2-burst quickly and kill orcas, but still does same overall damage as before. Uses missiles more efficiently by having them do lower damage and firing more often. 
Spread increased from 6 -> 12 since it is too weak against infantry. Damage vs. infantry still low, but at least has some effect vs. groups of infantry.
Increased RangeLimit, instead of increasing missile speed, to keep the building's flavor.
