- added a heightsec change when aborting the main trace due to having found a target in a subtrace.

- be a bit smarter about what to copy from a subtrace. There's 3 distinct pieces of information here: The hit itself, the CrossedWater setting for Boom-transfers and the CrossedWater setting for 3D floors.

Note: Ideally this should return all water hits it can detect, not just the first one.
