Add a "services domoticz.sh restart"-button to menu system for Admin

[ErnieFR]

I think this might speed up a lot of searching when things go wrong. I normally have a ssh window open to do a "sudo service domoticz.sh stop/start/restart/status" command on the prompt to get more information. But as you've added for Admin user a shutdown-button, you might as well have a Domoticz-status-button and/or Domoticz-restart-button! Just a thought.
