Stage 5: das-update and das-welcome (0.3.0)

das-tools (Go, GTK 3 via gotk3):
- das-update: update window, tray icon when updates are available,
  --cli mode; xbps-install -Su between a snapper pre/post snapshot pair,
  privileged part through pkexec, rollback and reboot hints
- das-welcome: first-login window with install (live), language,
  home folder renaming, updates, settings and help

das-settings 0.3.0: create home folders with translated names.
xdg-user-dirs 0.20 only looks for translations in the first
XDG_DATA_DIRS entry with a locale directory (/usr/local/share/locale).
