More read/write tests for town and outdoors, including maps/dialogue

Fixes:
- For towns, the "has tavern" flag was not saved or loaded
- Outdoor roads were not saved or loaded
- For outdoor encounters, the "can't flee" and "forced" flags were not loaded, and "forced" was not saved
--> These two flags have also been separated in the code
