Display 5 day forecast information. The format is as follows. For datasources that support a 5 day forecast. They must use 'Short Forecast Day #' for key and then q QString containing the fields: ForecastPeriod|ShortTextOfForecast|HighTemp|LowTemp|PopPrecent.

This goes for any 3rd party datasource that reports basic data back to the weatherengine. For advanced ions/datasources such as the Environment Canada ion, we also have a 'Long Forecast Day #' key.

The applet will be able to parse these keys and display the data appropriately later on
