add fdm.conf example

... sfeed_maildir, procmailrc and fdm.conf will probably be removed
and moved to a documentation file for clarity. The ways to use
sfeed to output mail in any format is available (via sfeed_mbox).

I'll assume the person who uses this has enough knowledge to convert
mbox to the format he/she wants.
