New embed script

Today we've updated the embed.js script and brought it into the 21st century... I mean, now it doesn't require me to "build" the script because it's loaded as a module, instead of having a million build steps.

The old way of embedding, if you're using it, still works without issue but will no longer be updated. So please take note of the new script tag found on the category page, or you can read about it here in the docs.
