Implemented the request handlers for data services, and added minor refactorings.
Path refactoring feature complete. Everything still breaks :-}
Introduced UriTemplate as drop in replacement for the jersey-thing-with-many-dependencies
Make sure dataservices are unloaded when deleting them. Fixed replace service; needle literal contains regex special characters, so quote it.
Fixed all the things

* Removed dependencies on jersey.
* Fixed url encoding (booh java)
* Make sure all services can be cleaned up neatly
* Fixed several tests
