Android Head Units

23 themes are documented here with no picture of what they actually look like. Most are the newest ZXW ones, which makes them the most interesting and the least documented.

To fill one in:

1. Open the theme's page. It generates the exact <Item> line to add to your factory config to make the theme selectable.
2. Activate it on your unit and take a screenshot of the home screen and the settings screen.
3. Send them on Discord, open an issue from the contribute page, or open a pull request adding home.png and settings.png next to that theme's index.md, which is the layout every other theme uses.
