Please add Deutsche Telekom Root CA 2 certificate to cacerts.pem
It would be nice if the "Deutsche Telekom Root CA 2" certificate could be added to Gajim's collection of root CA certificates. See:

https://www.telesec.de/downloads/DT-Root-CA-2.cer
This is the root CA for the certificates of many German universities and research institutes. It is also available in the Windows Certificate Store (and hence in MSIE), in Mozilla products such as Firefox, and in Opera, for example.
