TROR no-SE7 water: allow boundary change only if other-side lotag is other one.

Browse source 
That is, if submerging, the lower sector MUST have lotag 2. If emerging, the
upper sector MUST have lotag 1. (Previously, emersion happened from ST 2 sectors
unconditionally.)  This means that the area where submersion or emersion can
happen is now the same for the top and bottom parts.
