fix: add orgname and orgid parameters to access original room of lesson

[akaJuliaan]

Sometimes the room of a specific lesson is changed which looks like this on the WebUntis website:

In this example the lesson is in the room "OG2-3" instead of "EG-2". The WebUntis API does add two parameters to the room object of the lesson so it looks like:

{
      id: 130,
      name: 'OG2-DV1',
      longname: 'DV-Raum 1',
      orgid: 72,
      orgname: 'EG-1'
}

This PR adds the orgid and the orgname parameter to the ShortData object, that it is easy to access the original room where the lesson normally would be.
