[hibernate-dev] Checkstyle checks in ORM

While developing the Byte Buddy Enhancer, Rafael ran into what I thnk is a valid problem in the ORM build. Namely the fact that we incorporate non-fatal Checktyle checks. In local builds this leads to a situation where it is extremely difficult for new contributors to find out what exactly they violated. Jenkins presents these better and makes it easier to see just "fatal" (high priority) violations, but the Checktype report itself does not. Even worse the Checkstyle report does not even show the priority of individual violations at all. I suggest we remove all non-fatal Checkstyle rules to make it easier on contributors.
