Allow for disabling of locomotion features that may be cheats

[Cartrigger]

Hi! After a long while, we've started to run into players who have found their way around the settings, and have set their "Movement Speed Multiplier" higher than possible in vanilla Minecraft.
I would like a way to disable it via VSE / VS on server.
Another issue is the walking speed multiplier, because it can make it incredible difficult to hit someone if they slightly move in their room. (Slightly moving at maximum speed is extremely fast and basically impossible)
These should probably be disabled fully on servers that do not support Vivecraft at all (missing mod / plugin) and be configurable by the server on servers that do have it.

Do people really need to be jerks all the time?
