Auto-generated API documentation is not rendered for properties endpoints

[mdorf]

Currently, the API documentation generator maps the name of the controller (properties_controller.rb) to the original class that represents it. In this case, the class name becomes "LinkedData::Models::Property", which does not exist.

In fact, there is no one-to-one mapping for properties. Each property type is represented by its own class:

LinkedData::Models::ObjectProperty
LinkedData::Models::DatatypeProperty
LinkedData::Models::AnnotationProperty

Because the one-to-one mapping is absent, the documentation is not generated.
