Changes

• Now that we deprecated webpack and babel-loader, we're no longer using the kea babel plugin.

• Made the changes, went through each file to make sure there's no namespace conflict (e.g. "scenes.bla" and "scenes.bla.subbla" for logics would cause issues), and made sure it still runs locally. There were no conflicts and it ran locally.
• I could see all the paths inside the redux devtools now:
