Forecaster - visual, accurate 5.0.0

Dark sky is shutting down, so this release migrates Forecaster over to using data from the Norwegian Meteorological Institute. This means there are no more 60-minute rain forecasts or rain alerts, but the app will continue to work into the distant future. So far I've found the new forecasts to be more accurate than Dark Sky was.

Widgets are also now fixed, and the name of your location now appears instead of just saying 'current location'.

More to come...
