Do we need to change the Gulpfile at all? It's been a minute but I assume that's where those packages were being used?

I'm away or I would grep for them myself

I checked conflicts and I'm pretty sure the entire babel library is used just for a file called "webpack.config.babel.loader.js" to load the _scripts folder and it only needed babel loader which requires the entire babel library so I believe if a solution is found to load scripts without needing the babel library then we could remove babel

Still WIP, needs a solution for hashing scripts

I think discord discussions indicate we'd prefer to avoid rebuilding png images everytime as they by far take the longest, maybe only build the ones that aren't already in the images folder and then remove that from the gitignore.
