Project's repository URL in README.md has been updated and some other
minor changes have been done.

The REST API methods for entity creation and modification have been
simplified with more basic entities.

In addition, the UserResource class has been added so that it is
possible now for clients to use it for user authentication.

The change of the pets list in the owner to a Set makes it not
possible to use the pet's ids in the tests. Therefore, this commit
removes id comparisons for pets.

The project dependencies have been updated, including a change from
WildFly 8.2.1 to 10.1.0. This change affects the project configuration
in several ways, specially in tests configuration.

The README.md file has been updated to reflect the configuration
changes.

The tests code for rest and service modules have been reviewed to
simplify and make it more readable. This change includes some
improvements on the OwnersDataset and some matchers classes.

The IsEqualToEntity matcher (previously, IsEqualsToEntity) has been
improved to allow property comparison by functional reference to the
getter methods of the properties to compare. Specifically, the
"checkAttribute" methods added allow providing a Function<T, R> as a
getter, where T is the type of the entity to compare and R is the type
returned by the getter method.

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.

Some test classes have been refactorized for a more consistent use of
the OwnersDataset class and for a simpler test implementation.

This matchers makes the Response status easier to check in tests.

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.
