Made some updates so that we store a user's remote id, and started
implemented updated API routes.
A few tweaks so that the plugin sends order events correctly (passing
external_id).
Working on revamping how redemptions work to match the updates to the
API. We now define redemption options on the API, so the plugin should
pull them from there rather than building them locally.
Updated the redemption process so that it works with the new API! Yay!
Added a simple settings page so that api key and api secret can be
easily set.
Removed commented out API creds.
Talk to prod API endpoint by default.
