Removed an import of the class JacksonJaxbJsonProvider.class for JSON
converting. This class does not need to be added to the clientconfig
since Jackson 2.0.

Removed some System.out.println comments.

Removed unused stuff for the JerseyTest startup. Most of the stuff for
Jackson configuration is not used any more. They are probably
unneccessary after the update to Jackson 2.3.
