Refactor cLock to use the new Weather API

- Content provider was removed
- Weather sources (Yahoo and OpenWeatherMap) were removed. Those
  providers will reside in their own package.
- cLock was refactored to use the Weather API to process weather
  updates and city name disambiguation
- cLock will let the active weather service provider decide
  whether back to back requests are OK. In other words, cLock
  does not enforce the 10 min wait period between requests anymore
