This commit adds the JSF project with a web application that allows the
management of owners (by the administrators) and pets (by the owners).
The JSF project includes the functional tests for the owners management
page.

The EAR project only contains a POM that creates an EAR distribution of
the system.

The REST layer has been added but with incomplete tests. Students will
have to complete the tests.

This commit includes an important refactorization regarding tests. Test
classes and datasets have been moved from the "service" project to a new
"tests" project. This way, any project can include this "tests" project
as a dependency in order to have access to these common testing
resources.
