[FIX] mail: replace local links in notification emails

Since notification emails are not mail templates anymore they do not go
through the mail_template.render_post_process() method that converts
local links to absolute links. This means that buttons and images were
not correctly displayed in notification emails. Indeed those still had
local links.

This commit fixes that by moving the method directly in mail.thread and
calling it accordingly when rendering the notification email. Note that
the method has been changed in order to use regex instead of html
parser. It is done based on work already done in mass mailing application.
Indeed using parsers is complex and time consuming and may create
changes in the html structure that are not intended.

Next step in master is to go through various link modifications in
mass mailing module to see how to handle them properly. Maybe.
