Presence of .DS_Store dotfiles (Mac) in arches/app/media/js breaks webpack build

[jacobtylerwalls]

1. Open arches/app/media/js and use the (Mac) Finder to drag file icons around (e.g. to prepare to delete something)
2. Verify with ls -la arches/app/media/js you have a .DS_Store file
3. npm start in the usual way

result
