Integrate Affordance Aware

[kapil1garg]

CE currently makes a query to Affordance Aware, which is a Flask app running on another Heroku server.

To make the system easier to maintain, Affordance Aware should be integrated directly into CE. This would require a bit of re-writing code into Javascript, but since its mostly requests it shouldn't be too bad.

Make sure the debugging of affordances is as easy if we make this transition. It's so easy because we have a route to a server that returns back JSON
