- remove / udpate some paddings. Indeed some part of the notification emails
are badly aligned.
- postprocess the notification email to remove the content coming from odoo.
This ensure that action buttons present in some emails are not forwarded to
other people, notably customers. This is done by adding a div holding the
whole notification emails, with a summary = o_mail_notification. A summary
is used instead of a class or id because some html clients (like gmail)
strip classes, ids, ... summary seems to be kept in several clients.
