Jet library (core):

-------------------
* ORM DataModel: dataFetch* - raw mode added
* Jet Form:
    Form_Renderer_Single->setCustomRenderer( ?Closure $custom_renderer ): void
    Form_Renderer_Single->getCustomRenderer(): ?Closure
    Form_Renderer_Single->renderByView() : string

* Bug fix: non-functional internal relations in entity inheritance
* Bug fix: Form_Field_Data: invalid default error code
* Bug fix: Form_Field_Range: better input value catcher
* Bug fix: Form_Field_Float: null value if input missing
* Bug fix: Form_Field_Int: null value if input missing

Jet Example App:
-------------------
* ErrorHandler_Display: output buffer clean in a case of fatal error
