Spring 2023 CP Waterized

Spring 2023 modified:
- classic CPs turned into water CPs + in most cases added a ramp for smooth exit (not always),
- rectangular CPs - put water underneath, hard to explain, maybe should be more consistent there,
- upside down CPs - nothing done here,
- uphill CP on map 10 - nothing done here,
- uphill CP on another map - put water block a little bit before that CP because it was not that far.
