From 6401604a3bf3fadff3c3912a1443b16f8724d28a Mon Sep 17 00:00:00 2001

Subject: [PATCH] Move print generation to separate script.

For non-Mozilla browsers, use frames to separate headers from message
data.
Only show print links for parts that can be displayed in a 'full' render.
Re-add support for 'add_printedby' config option.
