Fixes for changes in bibliotheek.be API, #37
Because of these API changes, I notice the library name structure may have changed slighly for some libraries, as a consequence, the unique sensor name may have changed too, since it's using the library name.
The general markdown listing shown in the readme still works, as it's fetching the sensor names.
Some extra info now available in the changed API has been added as new attributes in the user sensor, readme updated.
