Deploy beta app

[kdbanman]

For final deployment, we need two servers:

• static file server for the compiled Ember app. "disquo.io"
• reverse proxy server for relaying CORS requests. "cors.disquo.io"

I see two options for this:

1. Both servers on the same machine.

Benefits:

• simpler DNS configuration
• could eventually be packaged into a single NPM module, with virtual host, proxy, and file server

Drawbacks:

• need a third server on the machine for virtual hosting between the other two servers, which means we need to be careful with request/response headers

2. github.io for file server, and dedicated machine for proxy

Benefits:

• reliable static file server
• easy to deploy application changes
• simpler dedicated machine - single server process instead of three

Drawbacks:

• code in two different places
