What's new in 1.2.0. A major update.

- Your data now lives in a real database. Existing messages and contacts migrate automatically on first launch, nothing lost.
- New navigation drawer you can pin open, with the channel list built in and in-place channel switching.
- GIFs share as links now, so people on other MeshCore apps can see them.
- Desktop remembers its window size and position.
- Reach contact settings from the long-press menu.
- Back-button, path decoding, and connect-speed fixes.
