Faster build

[Blackbaud-SteveBrush]

Turns out the build was pulling from node_modules, which is why it was so slow. There are a few other updates I'd like to make, but this should do for now.

@Blackbaud-BobbyEarl Alright, this is finally ready for review.

Just curious about the different syntax here.

[Blackbaud-SteveBrush]

It will ONLY look in the root's runtime folder, instead of "any" runtime folder.

Also, @Blackbaud-BobbyEarl it's recommended by Webpack docs to be more specific with loaders. https://webpack.js.org/guides/build-performance/#loaders
