Fix pale Wi-Fi/Bluetooth tray icons, das-panel-icon help, publisher and deployer (0.9.5)

- Light theme uses Papirus-Light: the panel icons of Papirus are #dfdfdf,
  made for dark panels (xsettings, theme index, login screen).
- das-panel-icon help/-h/--help print usage instead of setting an icon;
  unknown options are rejected.
- New packages publisher (publish) and deployer (deploy) on the desktop
  image: config in ~/.config/<name>/ (neutral example copied on first run),
  history in ~/.local/state/<name>/.
- das-theme 0.3.0, das-settings 0.6.0.
