Mail Manager can only handle 1 attachment at a time

[hachichaud]

In the email attributes, Attachments should be an array so that multiple attachments are possible.
Not really a problem right now, but will be at some point

See: https://github.com/ToucanToco/tc_mailmanager/blob/master/tc_mailmanager/mail_manager.py#L90

From the SendGrid API v3 doc, attachments is an array of object https://sendgrid.com/docs/API_Reference/api_v3.html
