Add ssl_ca_path to jabber connection.

[tobser]

this is needed for newer perl setups, I'm using 5.22,not sure if this
will break older setups..

Hey Tobi,

thanks for the patch. In case somebody does not have the 'net_jabber_certs_path' setting in the mh.private.ini and the folder /etc/ssl/certs/ does not exist, will this work or error out?

Best regards,
Lieven.

The path '/etc/ssl/certs' comes from openssl and it seems like most linux distributions have it, or it is a symlink to another valid path.
I have no idea if the parameter has any effect on Windows...

If the folder does not exist, the same error occurs as if the ssl_ca_path parameter was not set at all:
