This JSS patch is for the following bug:

Bug 816396 - Provide Tomcat support for TLS v1.1 and TLS v1.2 via NSS through JSS

It provides the minimum code to support setting the ssl version range from tomcatjss server.
The tlsv1.1 and 1.2 ciphers are made available as well.

There are other ssl range related NSS calls that could be made available in JSS, but it will be a separate task.

This patch works in conjunction with the tomcatjss patch that will be sent out shortly for review.
