This commit introduces a new wizard that allows adding existing contacts of a
specific mailing list to another mailing.list.
It's typically used on the list view of a mailing.list where you tick a bunch
of contacts and add them all at once to another mailing.list (existing OR new
one that you create on the fly).
That tool will help users manage their mailing.list a bit easier and avoid some
tedious copy/pasting if mailing.lists need to share common contacts.
Wizard has two options: either simply create a new mailing list, either create
it and use it directly in a new mailing. It allows to cover the following
user flow
* select contacts;
* add them in a new list created on-the-fly;
* jump on a new mailing targeting this mailing-list;
* fill body, launch, enjoy !
