Updater - Add checkbox to restart device automatically after update is finished

• /e/ version: 2.9 (and before) ... 3.0.4-s/-t
• Device model(s): Probably all

Please add something like a checkbox to the System Updater to perform a system restart automatically after the update process is finished (of course only when finished successfully). This will increase - in connection with that improvement - the update process and will minimize the required user interaction.
