Fix material you widget colors

[ukrbugreporter]

The weather widget does not use/uses the wrong material you colors. On the screenshot it's compared to other Material You widgets and it clearly does not fit in.

But aside from that, Prognoza is great and I absolutely love it. Hope this issue will be addressed soon.

Hi, thank you for the report and I'm very happy to hear that you're enjoying the app 🙂

I'm currently focusing all my efforts on the redesign, apart from some critical bugs that pop up along the way. Since this is just a UI bug, it will be fixed in the redesign.

The problem is I made the widget with an unstable alpha library that has odd bugs like this on some devices. The new version will use the old but stable API that responds to system colors correctly. For more info, see #45.
