Add new client code and demo for OpenWeatherMap to replace Wunderground as weather data provider

A few days ago Wunderground - the weather data provider we used in this library - has stopped their free tier without previous warning. We immediately started looking for alternatives and decided to migrate our code to use OpenWeatherMap.com as a service. This release adds the OpenWeatherMap client code as well as demos which show how to use it.
