In some case (ex: wrong email), it could be useful to be able to re-trigger the email notification manually.
This re-triggering should be allowed only if the condition of the trigger is still true.
A generic wizard (can run on any model) propose a selection of email notification that can be triggered for the selected records. Then it calls the
send_email for the notifications selected.
To activate this wizard on a specific model, the user will only have to add a keyword to the wizard action.
