Weekend upgrade

Just a few changes, but it took me two three days to upgrade. Here they are:

• SEO friendly links (for example, panoye.com/panorama.356-libourne-bridge-hdr.html instead of panoye.com/panorama-show.356.html)
• Images for java applet viewer (see the forum post for more info)
• ...and a few more minor enhancements...

Also, I changed the max file size to 1mb (from 2mb).

2mb images were too big for javascript viewer -- the image had to be resized after uploading. Since there were problems even with java viewer -- now four image resizes have to be made after uploading your panorama... One for javascript viewer, and one for java/applet, one for the thumbnail, and one for the mini-thumbnail. And that takes too long -- for some images 10-15 seconds!
