Registers a shortcode for fetching weather forecast from yr.no
The weather can only be presented as a table. That does not fit a widget. Yr.no has several formats to display the weater. It would be nice if the plugin supports them all.
In the shortcode it would be nice to have an additional parameter for showing also the weekday (Monday, Tuesday,...) in the table together with the date. Then it would be a 5 star rating.
