Handle command options with `Gio.Application.add_main_option_entries`

• Use Gio.Application.add_main_option_entries() to parse arguments.

• override handle_local_options() to show information, to make sure -v works in flatpak environment.

• override local_command_line() to check '--' option.

• disable the flatpak session-bus permission, ref the guide line: https://docs.flatpak.org/en/latest/sandbox-permissions.html#d-bus-access

  Access to the entire bus with --socket=system-bus or --socket=session-bus should be avoided, unless the application is a development tool.

• Implement the --tab option and handle multiple commands from options.
