The double persistence.xml in JSF and REST projects was causing
problems in some environments, as the tables were created twice.

This commit fixes this error by moving the persistence.xml to the
service layer.

The pet list "Edit" button was calling a method in the managed bean
that received the Pet entity. This caused lots of unnecessary queries
in the database. In order to avoid this, the edit method now receives
the pet identifier instead of the entity.

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 Bootstrap libraries (CSS and JavaScript libraries) were inserted in
the web pages (JSF module) through a CDN. Now, these libraries are added
as Maven dependencies, using the Webjars project packages.

In addition, the link and script tags used in the JSF template have been
replaced by the h:outputStylesheet and h:outputScript tags from JSF, as
this tags make consistent the use of relative paths though the different
pages of the application.

Finally, a minor error has been solved in the pets.xhtml file, as the
placeholder text for the birth field was assigned to the animal type
field.

The JSF 2.2 specification recommends using CDI annotations (e.g. @Named,
@RequestScoped, etc.) instead of specific JSF annotations (e.g.
@ManagedBean, @RequestScoped, etc.). This commit replaces these
annotations following the recommendations. This change has some side
effects, as now the container does not automatically recognizes the
/faces route and JSF must be configured in the web.xml file. The new
configuration now processes every XHTML page as a JSF and the /faces
paths are no longer required or recognized.

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.
