Add OpenID Selectors?

I saw [this JIRA issue](http://jira.grails.org/browse/GPSPRINGSECURITYOPENID-11) and thought it would be nice to integrate the [openid-selector](http://code.google.com/p/openid-selector/) project into the plugin.  The only concern I have is that it is BSD licensed and it has no license file included.  I have left the comments in the files from the project which note the license.
