KWeather: improve icon loading and other fixes

- Fix pixelated icons (issue #19)
- Fix "network offline" state
- Add helper `bool weatherDataAvailable(TQString stationID)` DCOP function
- Fix compatibility with old DCOP function signatures
- Prevent double "Network is offline" strings in weather data.

This commit introduces some new and renamed DCOP calls. Old function signatures
are kept for compatibility, but are mraked as deprecated.
