* When clicking on a button that is a preview for a "mass mailing",
always open it in a new window for the user that is editing the form, so
that changes are not discarded (when leaving the page).
- The option "Open in a new window" remains effective for the recipients of the mail.
* Rename Mailing Campaign to Campaign : this is just a mailing campaign,
they are used everywhere in the marketing scope now. And it can be part of
a multi-channel campaign.
* Show/hide mailings count depending on settings :
- Mailing Campaign must be activated in the email marketing settings in
order to display the Mailings count in the utm.campaign kanban view
* When there is no matching recipient for a mailing campaign,
properly display 0 / 0 instead of 0 / 1 to better indicate that it is
not expected that anyone will receive an email.
