Prevent ascension over max jump phase for normal jumping/moving.
Adds a "dirty"-flag, set on receiving velocity. If a player still ascends while exceeding max-jump-phase, a violation will be triggered, regardless of the taken distance. This has not been tested against hacks yet, and might well have little effect. It does aim against step and block-jumping on protected regions, but there might be another limiting method necessary to make this fully effective.
