Several testing improvement have been done:
	- Cobertura plugin was replaced by JaCoCo plugin that supports Java 8
syntax.
	- Unit tests with a controller fixtured using EasyMock were added for
PeopleDAO and PeopleResource.
	- POM was reviewed, reordered and reformatted.
	- Test classes naming was reviewed and standarized.
	- Three test suites were added to group the unit, integration, and
acceptance tests.
	- Naming context management done in TestUtils was improved. 

The java.util.logging.Logger was introduced as the logger for the
application.

Web configuration for REST services and login filter was moved from the
web.xml file to code annotations.

PeopleDAO functions now throw an IllegalArgumentException when an
invalid id or a null name or surname are provided. People's REST API
modified to return a "Bad Request" status when an
IllegalArgumentException is catched.

RESTful API modified to use PUT, DELETE, POST and GET methods.

In this first version, this applicacion includes a complete CRUD using
an AJAX+JSON+REST architecture.
