Changes:
- Added a setting for if the position data of the player is in its own "position" object
- Made checking for world data a setting for dynmap solutions that don't include a dimensions (mostly for earth maps)
- Added the option to specify the second part of the URL (after the domain) if the JSON file for player data isn't where I'd expect it to be.
Fixed a bug with waypoints not updating after being deleted/removed. Changed default url to the squaremap demo do mod doesn't immediately crash on first install.
