Refactored the three important builder classes, to be more firm with the
action which happens in this classes. Now the methods in the RESTful
service should be checked again for logical correctness.

Refactored the project, to work logically correct with the builder
structure.

ScenarioService needed a lot of changes to set the builder correctly.
Now they should work fine. The builder made problems in the WebUI. Now I
have a good knowledge of them.

Method name change: Changed setName in MeasurementSpecificationBuilder
to renameSelectedMeasurementSpecification.

Fixed a lot of comments, to have correct JavaDoc linking to objects and
methods.

The ExampleServiceRequest is abused to check the database data for a
specific user. It's now really an example now, but really useful when
debugging with the WebUI.
