Do not update/delete: Banner broadcast message test data
Do not update/delete: Notification broadcast message test data
Removes a hack that wraps every script in (function(){ ... }).call(window); for the sake of preserving sprockets behavior in scripts which take for granted that this is the same thing as window. Instead the scripts which rely on this behavior have been modified directly.
Make sure nothing has broken.
The imports-loader hack throws off sourcemaps and has some odd side-effects in babel like not allowing import/export to function properly.
