New securityonion-web-page and securityonion-elsa-extras packages provide more SSL visibility

A vulnerability in SSLv3 was recently announced (nicknamed POODLE):

https://www.imperialviolet.org/2014/10/14/poodle.html

In response to this, we recently added some SSLv3 queries:
http://blog.securityonion.net/2014/10/new-securityonion-web-page-package-adds.html

Today, we're adding some additional ELSA queries to allow you to see your SSL traffic grouped by version or by cipher.

SSL - Top SSL Versions

SSL - Top SSL Ciphers

Today's update will also reconfigure Security Onion's Apache instance to no longer accept connections using SSLv3.

The new package versions are as follows:

securityonion-elsa-extras - 20131117-1ubuntu0securityonion45
securityonion-web-page - 20141015-0ubuntu0securityonion2
