Celcius vs Fahrenheit in weather

This is an enhancement request.

Using entertainer 0.5.1, with location set to a UK city, I do get what look like reasonable forecasts [I haven't worked out which provider you are using to double check them], however the temperatures are unbelievably high - I am assuming they are real temperatures but in Fahrenheit.

Please add a weather configuration option to show forecast temperatures in either Celcius or Fahrenheit, set in entertainer-manager (since that handles setting the weather location).
