Make enemies more accurate

The general idea of having a separate "entity handling thread" is probably fine, but the exact contents of each block is almost certainly wrong.

Here's a summary of the current behavior:

Closer/Wuss
- Runs code every every 500ms
- Randomly moves one space towards any players it can kill within a 7x7 square
- If there are no players it can kill within this radius, run from any players with a sword/crown
- If there are no players in this radius, start moving towards home
Chase
- Code applies to EVERY CHASE ON THE MAP, and the code runs every update (no delay)
- Wakes up when at least one player has a shield
- Randomly moves one tile towards a random player with a shield

A few theories that can maybe be verified from existing footage:

My hunch is that ALL entities have separate sleeping and awake ranges, like how the snail is implemented
Entities may prioritize horizontal movement over vertical (the Crawl definitely does)
I don't think the "Flickering" or "Gone" states were ever used when entities respawn? The existing footage may just be too low frame rate to tell

First-hand accounts from people who played on Pixel's original server would be really helpful
