(uce-message-text): Change the text of message that is sent.
(uce-reply-to-uce): Do not assume all Received lines are on top of message without headers like `From' or `To'. (uce-reply-to-uce): Parse Received lines better. (uce-mail-reader): New user option. (uce-reply-to uce): Add support for Gnus. User is supposed to set uce-mail-reader to `gnus' if using Gnus to read mail. The default is to assume Rmail. There's no magic to determine what mail reader is currently active, so it is not possible to mix using uce.el with Rmail and Gnus.
