This is a pretty big change. This is mostly updating to Gnome 43 and changing a few things for review. Got some help from someone on Github and verified that it works on my machine as expected. I had a question from a previous review (of a fork) though; there was talk about destroying the `this._timeout` variable, what's the proper way to do that? I could submit another review with that change but the object doesn't appear to have a `.destroy()` method.

Erm, I realize now that I accidentally submitted a zip with a broken version of prefs.js, feel free to reject this one.

For timeout, you can add this to the `MullvadIndicator`: ```js destroy() { this._stop(); super.destroy(); } ```
