Zombie Players

Improvements to making zombies stay focused on their work in their work area
- Prevent playing while performing work
- Working zombies dont chase players for their food if in hand
- Prevent wandering outside work area
- Prevent chasing after dropped items outside work area
- Fix getting stuck depositing into full chest when theres other empty ones

Fixed zombies eating all the food they pickup while working if they are working without a tool, still still eat if it needs the food
Fixed some things not being trainable like create mod handcranks
Made zombies interact with things much faster if its the same block all the time (makes create handcranks work with zombieplayers)
Fixed setting work area getting stuck on 'removing work area'
Remove purple work particles to be less imposing
Faster starting of work after being trained
Fix hoe being used on blocks when setting work area
Stopped rendering nametags all the time and through walls, now its just when theyre tame and following you, or if you directly look at them
