Changes to submarine<->outside teleporting logic:

- contacts between limbs and the sub are temporarily disabled before teleporting to prevent the character from "exploding"
- impact damage is disabled for 0.25 seconds after teleporting in case the character still explodes
- characters with disabled impact damage won't damage the walls when hitting
- the collider of SubmarineBody is generated based on walls instead of hulls
- fixed Submarine.CheckVisibilit ignoring fixtures with (CollisionWall | CollisionLevel) collisioncategory
