#26 Check for existing draft on reply

[Gregor Rosenauer]

I think it would really be great if BeMail checked for
an existing draft (for a reply) when replying to a message.
Sometimes I forget I already started a reply and saved
it as draft, so I reply to the original mail and start
all over again...

BeMail could query existing drafts for the reference -
I think there was some reference-field in the Headers
that could be used, or alternatively a new attribute
"reference" could be used that holds the inode or name
to the original mail.

Thanks,
Hugh
