AuditProperty.isNotNull creates an incorrect condition in the MySQL dialect
---------------------------------------------------------------------------

                 Key: HHH-5718
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5718
             Project: Hibernate Core
          Issue Type: Bug
          Components: envers
    Affects Versions: 3.5.6
         Environment: 3.5.6-FINAL, MySQL 5.0.27, for apple-darwin9.3.0 
            Reporter: Anthony Bishopric
         Attachments: SampleEntity.java, SampleEntityDAO.java

When using AuditProperty.isNotNull(), envers will generate a sql condition "property<>null". This condition can never evaluate to true (it must use MySQL's "is not null" convention)

Attached are two example classes which should replicate the issue.
