[ADD] website: email_template: added website_link field, a link to edit the template
directly in the website
[ADD] website_mail: added controller and page to edit templates. They are still jinja
templates editable in the website. Not qweb templates.
[ADD] website_mail: JS file and editor override to enable only certain snippets. Those
are still to add, but will be base templates for email.
[IMP] website: improved the addition of editor JS in the template header to be able
to add JS file that override the editor without having to hack everything in the
template.
