From 1b5f527757ea7e6aa1ccc822c91449b541521a40 Mon Sep 17 00:00:00 2001

Subject: [PATCH] weather: update for newer GWeather

GWeather 3.6 changed API to be properly namespaced and GObject based.
Also, WeatherLocation was removed and replaced with GWeatherLocation
in all public API (with additionally the possibility to retrieve one
particular GWeatherLocation by station code)
At the same time, remove a old and now useless abstration by folding
EWeatherSourceCCF into EWeatherSource.
