Absence API: added attributes and filtering by "updated

Synchronising absences with Personio just became a whole lot easier!

We just added the attributes "created_at" and "updated_at", which indicate when a specific absence entry has been created and updated the last time.
You're now also able to filter the results by the "updated_at" attribute using the two parameters "updated_from" and "updated_to" (both inclusive).

Find more information in the API reference.
