New Traps Added. Pathing optimizations.

This update contains a few new traps;

• Acid Trap
  • Shoots acid, covering units in front of the trap in acid for a time. Units covered in acid take increased piercing damage.
• Bomb Trap
• • Explodes once units are in proximity, dealing a large amount of damage. Recharge for this trap starts once a barrel is deployed and will hold the recharged barrel in reserve until the active one detonates.
• Zap Trap
  • Electrocutes units standing on top of it. Can chain to other units up to a certain distance. Electrocuted units are heavily slowed for a brief amount of time.
