Merge pull request #430 from trap000d/weather_widget

Weather status icon fix; closes #428.

It looks like OpenWeatherMap have fixed most of issues in their API. Now they return sunrise and sunset times properly for current time zone, however the status icon is still wrong:

    transition N->D appears at 0:00 UTC (must be at local sunrise time)
    whereas D->N appears at local sunset time

So we still need to check if we're in or out from sunrise/sunset times, but no need to perform all other manipulations with dates and times.
