* 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.

Closes #87

Moves "resolveCodeElement" and "getCrossReference" out of the ImplementationLanguageDefinition, because it is not needed there

also removes unnecessary .fragment files

CoCoME2IAL now translates composite provisions and requirements as is, and does not automatically delegate them.
PCM2IAL instead translates that now.

Also: Fixes a typo in the menu items

* refactors the definition and use of the filename 9_cm2code.ids
* Creates a ChildTypeTransformation for JEE
* Creates a notation project for JEE
* Fixes errors in the references transformation handling

#83 Allows for selecting Implementation language for migration at interprofile transformation steps.

Not visually appealing atm
