Questown

Fixes:

• Critical: Stop clearing quantity/NBT in town chests
• Visitors could not sleep in a bed more than once. And the bed stayed occupied.
• Liquid blocks could cause a fatal crash during wall detection
• Progress messages should hopefully show up in chat when using a server
• Villagers will be hidden while their status is returning, regardless of position
• You can no longer click on hidden villagers
• Stop respawning villagers every morning (store town state on sleep)
• Clear bed occupancy for all villagers in the morning
• Disable collisions when villager is hidden

Adds:

• Town door item
• Logic to support town door item
• Persist registered doors on town flag
• Welcome mat blocks can now be associated with a flag by right-clicking the item on the flag
• Support preservation of quantity and NBT data on items in town chests
