Title: Fix for heartbleed ssl vuln in docker image

### Adds multiverse without removing security updates
This pull request changes how the `multiverse` distro is added to `/etc/apt/sources` such that the `quantal-updates` and `quantal-security` repos are not overridden. Without this change, the installed `openssl` version is vulnerable to the [heartbleed](http://heartbleed.com/) bug.
