Organize the repo and export profile module properly (#262)

* Moving files to their new homes.

Subsequent commit will wire everything up again.

* Relink files and split stylesheet.

Requires adding resolve-url-loader to fix sass import relativity.

* Remove browserslist warning.

* Remove the need for ProfileMain

* Fix test issues - needed thunk.
