Changes the WildFly testing ports
The ports used by the WildFly executed during tests had an offset of
10000. This was the same offset used by the other tools in the
integration server, causing port collisions in the integration server.
This commit increases the offset to 30000 in order to avoid this port 
collision.

Adds events persistence to the EventEJB
The EventEJB class now can persist events. This commit also includes an 
important refactorization of the entity classes, that have been moved to
a new and more adequate package. In addition, the dataset classes for
user and event have been created.
