Changes:
- Added bed assignment UI for easy swapping of beds.
- Villagers gets saved and reset after 5 minutes instead of 30 minutes when the player goes offline for lesser lag on the server and faster "debugging" of villagers.

Fixes:
- Optimized villagers, so that they cause lesser lag on the server.
- Nearby town loading radius reduced from 300m to 200m, and unload town radius increased from 500m to 600m.
- Dead bodies had a collision that blocked arrows and bullets.
