Editing a mailer class, doesn't save data

[jcheron]

from @gildonei

1. Click on "eye" button on created Mailer Class (step before)
2. Click on "edit button"
3. Fill the new data
4. Doesn't exist a save / update button, close button just close and cancel, send button just send, but don't save data
5. Attachments dir, can't be filled

In this case, it is a question of editing an email that is dynamically produced by the associated class (which the developer will have coded to do what he needs).

Editing just allows to make some corrections before sending the dynamically produced email.

This statically modified email can be sent, and it is then saved in the dequeue (sent mails).

The attachmentsDir should not appear.
It still lacks the possibility to statically add files (and thus upload them)
