Do not use profile name in subject line

[Minim]

Messages sent with Deltatouch are still showing that encrypted subject line (I’m looking at them in Neomutt). If you want to know if they change with changes in profile name, I’ll check. I think the long-term plan is to make them user-configurable in the interface:

Subject of emails

Changing the subject, as well as attaching multiple files at one message, are two features that are absolutely needed. Like any IMAP client, somehow they must be implemented. Please work towards this direction. These are the only reason not to have delta chat in my oppinion, as this is a great idea otherwise!
