* The old datatables-servlet2 dependency has been removed from the pom.xml
 * Some attributes have been renamed (e.g. paginate => pageable)
 * Starting from the v0.10.0, all web components (servlet, filter) must be explicitely declared in the web.xml file. That's why I added the following declaration: DandelionFilter, DandelionServlet and DatatablesFilter
 * Added a new datatables.properties file in order to disable the asset management brought by Dandelion-Core. This is equivalent to the old cdn=true table attribute

adding explicit reference to default profile because it doesn't seem to work on on some environments

In that way we don't need a dedicated config file for the Service layer

- web.xml is now simpler
- mvc config file has been split into 2 files

- 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

+ move spring application context files under a dedicated folder (to prevent JBoss XML parser from choking)
