Refactoring: use Exception mappers instead of try catches in resources.

[alexnederlof]

Currently there's a lot of try/catches in Jersey Resource classes. In general these exceptions should be handled by an Exception mapper. This cleans up a lot of code and should unify our returned HTTP status codes in case of exceptions.
