Ship to ship Collision missions

• Ship to ship collision missions: missions involving collisions of two vessels
• The mission would almost have at least one big ship (i.e. a small ship has hit a big ship, or a big ship has hit a small ship)
• The position of the collision would have a very low chance of being known, the player would have to find it in a search radius
• The ships would spawn with damage and some amount of water already in them
