[IMP] mass_mailing: add 'view in browser' link in mailings

PURPOSE

Add a block that allows recipients to check the email in a browser in case
their mail service provider does not render it well or to see it full screen.

SPECIFICATIONS

A thumbnail has been added in the snippet thumbnails list of the mail editor.
It allows to add an header snippet. This snippet contains a link allowing the
recipient to see the mail in its browser instead of its mail client.

Add a route to display a mailing content. This route should be recipient
dependent as mailings could contain jinja markers. Using the same access token
and check as unsubscribe route this public route allows to display a mailing
content directly rendered for a given customer.

_get_unsubscribe_url method is moved from mail_mail to mailing as it does
not really belong to the mail model. Indeed it is mailing dependent.

A view URL leading to the view in browser route is added. It is managed like
the unsubscribe url: magically avoid shortening, magically rewrite when
sending email.
