The reference to the jarfiles in a persistence.xml is now templated; it is set by maven
Add a new junit rule to set up a database for the integration tests implying the persistence engine of Silverpeas.

This rule is now used by all the tests that extended RepositoryBasedTest class; this class is now deleted as unused
Rollback my way to manage the include of others jars into one persistence unit for the tests implying the peristence engine of Silverpeas
