The SimpleModel is used to to read simple data models from YAML that require no further processing
This allows us to delete several models that re-use the same code.
In the new data model, some field operate as keys for other parts of the model.
This now performs some validations and will throw an error if fields are missing.
For example: a Game must have an Engine, but does not require datafiles
Update the compatibility page to use the new data models.
- Notes are now generated based on game ids, platforms and support level
- We no longer need multiple compatibilty files, only the deltas in one file
- Support level text is now localizable
- Keep support for the old model for versions < 2.0.0
