The functionality to add an event on outlook through a link seems gone on Microsoft's part
Or doesn't work as it did before
To avoid confusion, we remove the links

changed the odoo interface violet by changing the main LESS variable
but forgot there was many direct occurences in XML/HTML/... (for
example for the mobile browser color).
Even if it's community the odoo interface violet is used at many places
(module description, XML demo data, ...).
As we will soon improve the sanitizer we will be able to sanitize email
templates body. However this implies some cleaning in the templates to
be sure mako is not considered as invalid html / xml and therefore removed
from the template body.
