Subject: [PATCH] Add '/paper mobcaps' and '/paper playermobcaps'
Add commands to get the mobcaps for a world, as well as the mobcaps for
each player when per-player mob spawning is enabled.
Also has a hover text on each mob category listing what entity types are
in said category

Subject: [PATCH] Replace ticket level propagator
Mojang's propagator is slow, and this isn't surprising
given it's built on the same utilities the vanilla light engine
is built on. The simple propagator I wrote is approximately 4x
faster when simulating player movement. For a long time timing
reports have shown this function take up significant tick, (
approx 10% or more), and async sampling data shows the level
propagation alone takes up a significant amount. So this
should help with that. A big side effect is that mid-tick
will be more effective, since more time will be allocated
to actually processing chunk tasks vs the ticket level updates.
