WIP: Check form naming in coding style
Checking conventions for form, dialog and reports based on https://web.archive.org/web/20140318125244/http://www.erp5.org/GuidelinesForNamingConvention#ERP5_Form
Checklist:
- make sure the old convention is in https://www.erp5.com/documentation/developer/guideline . It seems this part about skin is missing
- maybe make an ignore list of all the current forms that we don't want to rename for compatibility
