[imp] Insert custom headers and subject to compose window

[Lars Bungum]

I'm going to use IMP as the basis of an IMAP-driven customer relations
system (ticketing).  For this I need to insert custom headers, and
append a ticket (just a numerical ID) to the subject line of the mails
that are sent.  How can I send this as a variable to IMPs compose
window?
