board loading messages

During the start-up of a pad we show a loading message with hints. We have adapted /opt/etherpad-lite/node_modules/ep_loading_message/loading_message.js to include:

const messages = [
  "<p>FAQ 1</p> <br> Use Control key and S to mark a revision for the timeslider.<br>&nbsp;<br> Benutze Control-S um eine bestimmte Version im Zeitverlauf zu markieren.",
  "<p>FAQ 2</p> <br> Boards are automatically saved in real time <br>&nbsp;<br> Boards werden immer sofort gespeichert",
