Add PoR zone linking support

[xackery]

This introduces support for the Prophecy of Ro zones.

This is currently a draft as I'm still testing all the zone points and linking.

• I have a .sql file I'm preparing to fix all zone points as well, and will see about getting that into PEQ's db around same time this PR is completed.
• Feel free to give input on general structure and design. We still haven't made an .editconfig to enforce a standard, once we do I'll convert to that.
• I'm not sure if we want ; on lua, or () on conditionals, I'm happy to follow a standard but seems quests isn't very standard anyways
• Tab 4 ?
• Renamed all zones from "magic numbers" to lua zone consts where applicable of being changed

Closing for now. I was getting feedback but there's significant work needed to fully clean this up.
