Finally get printed CSS working entirely properly

Finally get printed CSS working entirely properly

It turns out @page can't go inside of an @media {} block. I should
have expected this, but such is life. Fixed a few typos and made the
box borders in the printed output 0.5mm (again). Printed output of
various pages looks tolerable from Konqueror 4 and Midori, but good
old Mozilla is still lame. Time for Mozilla to go the way of Internet
Explorer I guess... except Mozilla was always a bloated piece of shit.
