[evolution/webkit: 55/196] Apply the ordering of headers to the generated message

[Dan VrÃtil <dvratil src gnome org>]

commit 0dfb4a301e3623b9cfbaf9a492d00f5c5ff444ef
Author: Dan VrÃtil <dvratil redhat com>
Date:   Wed Jan 4 12:24:06 2012 +0100

    Apply the ordering of headers to the generated message
    
    TODO: the message is still not reloaded before actual printing, so the changes
    in headers are not visible on the printout.
