Publishes weather forecast messages based on the last known location provided by OwnTracks. The default location if none is provided by OwnTracks is injected on startup by the 'default location' node.
The forecast messages are published to the MQTT topic notifications/weather where they can be pushed to a mobile device by mqttwarn.
Multiple users are not yet supported, the location is stored in global.location.$username as {lat: "xx.xxxx", lon: "yy.yyyyy"} JSON object.
