Implement XDG compliance, logging, and improved 401 error handling

- Install to ~/.local/bin/winamp-mpris
- Use ~/.local/state/winamp-mpris/bridge.log for logging
- Use $XDG_RUNTIME_DIR/winamp-mpris.pid for PID management
- Add detailed user notification for 401 Unauthorized errors
- Add install.sh for automated, standard-compliant setup
- Include Winamp Web Interface source code and installer in repository
