[Feature Request] Indicate dusk and dawn times

Hello, i think it would be quite useful if we could display times of upcoming dusk and dawn using xfce4 weather applet... Both on tray and in the main window.

Thanks for considering this.

changed title from Indicate dusk and dawn times to [Feature Request] Indicate dusk and dawn times

added 2. Feature label

You can download sunrise and sunset data from met.no. But please don't make more than one request for each day, as the calculation results are constant.
