Per-player Fahrenheit/Celsius switch based on geo-location
- Temperature of users coming from a country that uses Fahrenheit will now automatically have their temperature displayed in Fahrenheit. Only works on first join and players can toggle back to celsius if they want. Also works the other way around if Fahrenheit is the default on the server. The country is detected using the IP address of the players.
- Some bug fixes for /togglefahrenheit while Fahrenheit was the default on the server
