New login method based in HTTP's Basic Authentication used. This new
method eliminates the need of the database supporting the SHA256
algorithm and facilitates the future use of Basic Authentication.

Tests were updated to use the new token encoding.

DAO class modified to support and alternative JNDI for the data source
through the "db.jndi" system property. A new testing database resource
was added to the Context.xml file.

DAO tests use the "spring-test" library to create a JNDI context, as
JUnit doesn't create any context. Additionaly, a custom DataSource is
created using the "commons-dbcp" library and injected into the context.
Testing database creation scripts are provided in the mysql-tests.sql
file.

REST API is tested in the server side using the
"jersey-test-framework-provider-grizzly2" library. These tests also use
the "spring-test" and "commons-dbcp" libraries to create a context and
inject a custom data source.

REST API is tested in the client side using the "Selenium IDE" and
"RESTClient" plugins for Firefox. Manual database reset is required
before launching the test suite.

Web interface is tested using the "Selenium IDE" plugin for Firefox and
using the "Selenium WebDrive" in JUnit tests. Same tests are implemented
in both cases. Selenium IDE tests require a manual database reset before
launching the test suite. JUnit test require the server to be started
using the testing database.

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.

LoginFilter modified to send redirect when login is done with parameters
and to return a 403 error when accesing Rest API without authorization.

Access to any resource except index.html can be restricted enabling the
LoginFilter in the web.xml configuration file. It is currently disabled.

Old index.html moved to main.html and replaced with an index.html that
contains a login form.

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.
