Fixes:
- Added the Reload Town button in the world map town menu, that rechecks the town's server checksum with the client's and loads missing levels.
- Revamped the town saving and loading with a new checksum-styled system that also saves the town's blocks into the client's ClientSave file, to speed up loading of town blocks when there are no differences within each level.
- Summary slot of a dead villager not being removed.
