Newsletter

I also fixed a LOT of broken links in older newsletter folders (.html instead of .php, old paths that were replaced 3 or 4 years ago...)

Newsletters from late 2006 and all of 2007 didn't have index.php pages, so I copied HTML from the newsletter/archive page into new index pages for each issue in 2007. Still need to do 2006.
