The new root certificate will be needed by the python and PHP clients
to allow them to connect to the UTBS when its certificates are
renewed, since they will be signed by a new root.

No change needed for Java clients, provided that they are running on
Java 8u91 or later, which ships with this new root certificate.

Also updated the Javadocs to build with Java 1.8.

Tagging this as release 1.1.1.
