Changelog

Overall I've been fairly busy tinkering on the site today. I modified the layout and made it nicer looking (broke mobile view in the process, but I'll tackle that problem soon) and I added this! It's been a hot minute since I did anything with web design prior to this site and I forgot just how finicky CSS can be. I also figured a changelog would be a good way for both myself and visitors to keep track of changes that have been made and things that have been added.
