[FEATURE] Add SENDER E-Mail Header via TypoScript

Adds the possibility to set an SENDER Mail Header via TypoScript
according to RFC 2822. So along with FROM: and TO: a SENDER: will
be added to the mail-header. There you can add the Servername and
an Mailaddress which is technical responsible.

F.e. this is needed to circumvent SPF issues when filling FROM:
with the mailform senders email address.
