[Evolution] feature req: "forwarded icon"

[Jon Nall <nall pa dec com>]

hello.
you know how when you reply to an email, the icon changes to an envelope
w/ and arrow? would it be possible to add an icon with a different arrow
(pointing the other direction, a different color, etc) for mails you'd
forwarded? it doesn't seem like it would be tough, but i'm not familiar
with the code.

thanks.
nall.
