`fab test`

Addresses https://bugs.launchpad.net/oq-platform/+bug/1226057.

One of the faulted_earth tests will not necessarily pass, and requires jpype and OpenSHA-lite to be installed and set up in the environment. This will be addressed later and is out of the scope of this pull request.

Once this branch is merged, we can enable this Jenkins job: http://ci.openquake.org/job/master_oq-platform/
