I consolidated the web site's various script functions into one "Grand Unified Script," and automated a few more things. This will simplify future updates, particularly when adding photo galleries. I've left the old scripts in place because I didn't want to update every bit of content on the site, and this way old stuff hopefully didn't break. Everything I've tested so far works well.
