Removed old plugin repositories

To prepare for the update all the plugins and dependencies
Removed all dependencies before updating
Reformatted pom.xml file to increase readability
Updated maven-compiler-plugin to target Java 7, show deprecated APIs and show warnings
Set a Jetty version
Added gitignore

Exempt Maven target directories
Updated the JAXB plugin to a different more up to date version
Updated all needed dependencies
Updated web.xml to enable transformWsdlLocations

transformWsdlLocations allow spring to use relative locations for WSDLs
Added annotation-based SWS configuration and component-scanning
Removed beans and their usages

Removed beans and there usages. Replaced the beans with the replacement
SWS configurations. Added annotations to the endpoint to be able to use
annotation-driven endpoints
Changed the DAO to use a injected EntityManager

Also had to enable Spring Managed Transactions, this was needed because
the LocalEntityManagerFactoryBean does not manage transactions on
itself.
Annotated the CalculationDao with @Repository

This allows the component scan to automaticly pick it up, so a bean
definition is no longer needed.
Accidental usage of the hibernate version instead of the spring version
