Add newline at cert concat

I got an error that haproxy can't load the cert. I looked into it and saw that the two parts are concationated together without a newline. 

Wrong:
-----END CERTIFICATE----------BEGIN RSA PRIVATE KEY-----

Correct:
-----END CERTIFICATE-----\r\n
-----BEGIN RSA PRIVATE KEY-----

It works for me now...
