CodingStyle: implement a basic ERP5Form.checkConsistency

Checking some conventions for form, dialog and reports based on
https://www.erp5.com/documentation/developer/guideline/programming/
and https://www.erp5.com/documentation/developer/guideline/module/

For now we implement only a few checks, we will extend later.
