Fix (or a workaround) to characters teleporting inside/through colliders when leaving a sub (see #552). Gaps do a raycast out from the sub to see if there are obstacles outside, and if so, ragdolls place a collider at the corresponding position inside the sub. The collider is simply a straight axis-aligned line atm, so it doesn't work accurately with sloped ice/submarine walls, but does prevent the ragdoll from ending up inside the obstacles. TODO: use a few edges to approximate the shape of the obstacles more closely?
