[REF] mass_mailing: rename mail.mass_mailing.{.contact{_rel}, list{.merge}} models

PURPOSE

Mass mailing is currently a bit messy. As SMS will be added as a way to notify
people in mass through SMS let us take this opportunity to somehow clean this
application: organization, light code cleaning, model renaming.

SPECIFICATIONS

Rename mail.mass_mailing.list and mail.mass_mailing.list to mailing.list
and mailing.list.merge. Rename mail.mass_mailing.contact to mailing.contact.
Rename mail.mailing_list.list_contact_rel to mailing.contact.subscription.
Rationale :

  * those new names are easier to understand: mailing.list and mailing.contact
    are less mail-related, especially taking into account that SMS will allow
    to be less mail-oriented;
  * those names are easier to read / find / understand;
  * align wizard and sub-models naming with the main naming;
  * have a mailing as first part of namespacing;

MIGRATION

mail.mass_mailing.list model -> mailing.list
mail.mass_mailing.list.merge model -> mailing.list.merge
mail.mass_mailing.contact model -> mailing.contact
mail.mass_mailing.list_contact_rel model -> mailing.contact.subscription
mail_mass_mailing_contact_list_rel table -> mailing_contact_list_rel (specific
case of a decorated m2m)

fields updated (no column change)
  * mailing.list: subscription_contact_ids -> subscription_ids
