Domain change + new features

Our first set of website updates!

• Changed domain name from 'horni.io' to 'horni.games'. Personally, I still prefer the .io TLD, but they technically don't allow NSFW, as was informed in the last club meeting. I reached out to them in the hopes of changing this one day, but going to launch with .games for now.
• Image upload max size increased from 2MB -> 10MB
• Though the website still doesn't support resizing gifs, it does now return the original gif file when looking at the full image. This can be useful for embedding 'inline' type animated images. There's still a max 10MB limit -- tools like GIF Optimizer can massively reduce gif sizes.
• If your images are already uploaded somewhere, there's now an option to download from URL instead of uploading file.
• Fixed some bugs with tags that have '&' in them, most notably point & click
• Added a page that lists the tags on the site.
• Got most of the games from the club added to the site. I did my best tagging them, but you know your games better than anyone, so please do feel free to go in and adjust!
• More consistent result ordering on various pages
