New Stack Wallet release for all currently supported platforms. Version 1.7.8, build 172.

Release notes:

- Themes have been redone. Now only light/dark ship with the app. If you're on another theme and you update you'll be switched to light. Worry not though, go to Settings > Appearance > Add Themes to download only the themes you want from our theme server (saves space). And yes, our theme server is FOSS too (and you can even make and submit a theme to it): https://github.com/cypherstack/stack-theme-selector-server

- Moved address book to isar database (was still Hive)

- Epic Cash now fully functional on their new codebase

- Fixes for Firo and Bitcoin Cash

New Duo also released. Details in a separate post.
