Allow enabling sand duping (#10191)
Because this exploit has been widely known for years and has not been fixed by Mojang, we decided that it was worth allowing people to toggle it on/off due to how easy it is to make it configurable.

It should be noted that this decision does not promise all future exploits will be configurable.

Subject: [PATCH] Rate options and timings for sensors and behaviors
This adds config options to specify the tick rate for sensors
and behaviors of different entity types as well as timings
for those in order to be able to have some metrics as to which
ones might need tweaking.
