Allow our users to modify mail template more easily
- make the list accessible from the settings
- give them a link to update relevant views to update header/footer
- make the list and form of templates more readable
- add a description on templates, allowing to describe their usage
In order to better filter templates, a new category field is added that
is computed based on active flag, description being set and the template
having an xml ID. Master templates are active, with a description and an
xml ID.
Update master data to add description on some templates.
