Spring MVC

Changes services to use Spring MVC instead of Jeeves.

• Easier to develop, also for new developers. Widely used framework.
• Easier to support i18n (internationalization)
• Make it easier to develop plugins (make GeoNetwork more modular)
• Easier to support multiple output formats (json, XML, PDF, HTML etcetera)
• Good integration with Spring JPA and Spring Security frameworks already used in GeoNetwork
