Spring Updates

Hi again Craig,

I've updated some of the projects here, mostly around current Spring version.  The Spring31, I just updated to 3.1.3.  I added a parent pom for all of the XmlHater projects.  Converted all Sysouts to use Logback.  

N.B. I had updated Guestbook here from an old checkout I had, after I checked it in, I found ou had moved that project, thus my previous pull request for Guestbook.

Regards,
Gordon
