(rmail-output): If file is an Rmail file,

use rmail-output-to-rmail-file.
(rmail-output-to-rmail-file): If file exists
and is not an Rmail file, use rmail-output.
If we find an element in rmail-output-file-alist, eval it.
(rmail-file-p): New function.
(rmail-output-file-alist): Now contains expressions to eval.
