Codegen: public field vs getter/setter

[n614cd]

For generated models, the use of getter and setter functions actually makes the code hard to read, and further costs additional performance time versus straight field setting on transaction focused systems.
Therefore to reduce code complexity, make it easier to read, avoid the use of the call stack to set a single value, I now make use of public variables on model/entity objects;. I reserve the use of getter/setter when actual logic must be implemented on a specific field.

Therefore, I would like two new configuration options. One, a simple flag to generate models with public variables instead of getter/setter. A second which contains a list of object + field where I want to force the generation of the getter/setter.
