enable JTA via UserTransaction handling

This means that we must not manage connections ourself anymore but only
via UserTransaction. This is the reason for the @Transactional inner classes
in the unit tests.
enable propper logging over log4j

This now works even for jul parts like MyFaces and OWB.

fix AccessVoters
store batch information in the database

The following batchee Services got activated via batchee.properties
* JPAPersistenceManagerService: enables storing batch artifacts in the database via JPA
* ContainerManagedEntityManagerProvider: provide an EntityManager which gets resolved via @PersistenceUnit(unitName="batchee")
add comment for the various batchee.property settings
provide own EntityManagerProvider

Having this in batchee itself was not possible as it only would work
if the persistenceUnit really exists in persistence.xml. Otherwise
a deployment error will be thrown.
