Revamp backend code to support good local function development (#657)

* Move concurrently dep upwards

* Add express as explicit dependency

* Accept just one HTTP method per endpoint

* Fix endpoint option coalescing

* Expressification of cloud functions

* Nicer logging of API requests

* Refactor web package.json

* Add ts-node and nodemon to dev dependencies, bring back cors

* Add scaffolding to point dev server at local functions

* Enable emulator in dev server scaffolding

* Fix up a little stuff I broke
