Add comprehensive build script and fix quality issues

- Add build-all.sh for complete build process
- Add icons.ico for Windows (needs rcedit for embedding)
- Add tickstales.desktop for Linux menu integration
- Configure packr to use icons.icns for macOS
- Copy icons and version metadata in build script
- Linux build now includes .desktop file and icon

desktop/build-all.sh
