Documentation

We need to document

• it is now possible to use form_widget(form) to render whole symfony forms
• explain why form_widget() is so much better (especially the fact it can be used to completely reorder/modify template rendering without template override)
• explain how tu use CustomContentType, when to use it, when not to use it

Uniformize rendering of all forms

And we need to modify the twig templates for all Symfony forms to use a single form_widget() call, instead of rendering each widget in a dedicated manner.
