Here's my fix for issue #1939. It's able to combine all projects into a single zip file but we're going to need to do a serious refactor the bundleExternalLibs() function in project.controller.js if we want to add external dependency files to each project. I'm also not sure about the placement of the "Download all" button on the sketches page. Thanks

Managed to add external lib bundling to bundled project files without doing any major refactoring after all.

If there is anything I can do to help get this feature over the finish line, this is something I'd love to see. It is also similar to this PR about downloading collections as a zip: https://github.com/processing/p5.js-web-editor/pull/1997
