Subject: rest: Add /client/move

Add URI to allow a POST request to move clients to a new room/folder.

Request POST /client/move:

    {
      "clients": [
        "192.168.56.11"
      ],
      "room": 10,
      "folder_id": 0,
    }

If folder_id is zero then that means computer is not stored in a folder.
