* Some Names aligned to thesis
* Removes unused IntegrationMechanismTransformation
* Corrects Type Hierarchy of some mechanism transformations. They used AMCT as super type before

renames "get" to "resolve" in the id registry, where an actual resolving happens + some more refactoring

Aligned with the thesis

* contents of mechanisms.tests moved to language.base.java
* createRootTransformationInstance now has zero parameters
  It is configured automatically in JavaBasdImplementationLanguageDefinition
* priorRegistry and language definition now owned by AbstractModelCodeTransformation

Also moves the mechanism translations from the mechanisms-project to the language base java project

Changes the name of the transformation manager to "core" to better reflect the content. Also aligns package names.
