Following bee3253b44, this commit is made
to increase the mail clients compatibility for the mails that are
created with the odoo mail editor.
Three new problems are handled:
- Font family of titles had to be forced too as outlook was not
inheriting parent font family on those either.
- Default text font-size had to be forced as was not detected in
transcoding correctly.
- text-decoration rule was decomposed in text-decoration(-line,
-style and -color) in transcoding. Outlook is ignoring those
three rules for some reason. As the decomposition is useless,
the transcoder now forces the recomposition of these three rules.
