What's new

Completely revised the way the desktop application is started on Windows, Linux and macOS (Bug #38). Dedicated start scripts, AppImage support for Linux and improved packaging make launching the application more reliable across all supported operating systems. Updated the Android target API to the latest version so that the app remains available in the Google Play Store. Updated external links in the help pages.
