1. split `auth.js` up so it's 1 reducer per file
2. consolidate the conference schedule reducers
3. make conference reducer names more descriptive
4. add error handling for `body === 'undefined'`
Thanks @rschamp for all the help!
Use a model of reducer/action files for each component that has them, and make `reducer.js` be the one that imports and configures all of them. This modeling is based on a few examples I've seen which seemed to work for our current case, but I'm totally fine with splitting actions and reducers into separate directories if we'd like too.
