function print_rewrite_urls in Printer, email and PDF versions 5

Same name and namespace in other branches

1. 5.2 print.module \print_rewrite_urls()

We need to manipulate URLs in two manners, depending on the state of the Printer Friendly URLs setting: 1. When on, we need to show the original URLs, making sure that they are absolute (even anchor names). 2. When off, relative URLs must be transformed to absolute URLs, including images, but not the anchors.
