Removed the optimisation of hiding the week number at a certain size
for consistency with the responsive design of Odoo enterprise. It is a
non-functional optimisation as it hides useful information that hardly
takes up any space. It also causes incompatibilities in the design with
extensions that do not take into account these specific changes.

We give a color clue to the users so they can better tell if they're
sending an internal note or a public message.
Dislaimer: we use the `has()` pseudo class mainly because is simpler to
implement and the support is quite extended right now. Even Firefox will
catch up soon (now it has support behing a config flag).
So users with compatible browser will enjoy it, while others will just stay
as they were.
