Upgrade to 3.5.1 and integrate other pulls

Included https://github.com/openshift/wordpress-example/pull/26, also fixed it so that the first time you deploy wordpress you'll get the install page (which removes the need to set the password in the db or hardcode the description).

Also integrated the changes from the security upstreams for OpenShift (where we autogen the config) and moved that file to its own directory.
