Server/Settings: Apply rules for a player based on where they are in the world

[assofohdz]

Acceptance criteria:

Implement or update Settings-system to allow lookup of settings based on world location. Other systems will call this system to lookup rules (e.g. physics, how fast should the player move etc.). Should return a "rule" object of some sort (or maybe just primitives?)

Scenario:

1. Player is located in a no-map zone (either no map is loaded or player is outside loaded map bounds), server default rules apply
2. Map is spawned where player is, rules reset to fit new map rules
3. Player moves out of map and default rules is applied again
4. Player moves between maps, rules updated on border to fit new map
