- test didn't have the suffix "Tests" so it was not taken into account
when running Maven in the comand line
- the POM was not configured so it can find Spring config files placed
inside src/test/java

see: https://jira.springsource.org/browse/DATAJPA-292

- migrated to Spring 3.2.1
- added hamcrest to the POM so it can be used with the Spring MVC Test
Framework
- Started migrating a JUnit test to Spring MVC Test Framework (at this
stage, it stills doesn't work. It could be because of a conflict with
ContentNegotiatingViewResolver)

also renamed some local variables in Unit tests

renamed profiles and removed unnecessary@DirtiesContext annotation so the Test suite now runs in 40% less time

- there are now 3 data access implementations (jdbc, jpa and
spring-data-jpa)
- added corresponding bean profiles
- JUnit tests are now successful

There is still some polish up to be done.

- migrated to bean validation annotations
- merged to one single controller

- removed unneeded Spring config files
- moved i18n files to a dedicated folder

- added JPA annotations to POJO classes
- merged JPA Repos with Hibernate repos so we only use JPA
- renamed .txt files to .sql
- moved Spring configuration files so it is easier to use them inside
JUnit tests
