Title: Don't let Rack::Static send a response until after we introspect a response from the API first

This is my fix for an message I posted to the group. However, the message appears to be gone. Otherwise, I'd post this pull request to it.

Don't let Rack::Static send a response until after we introspect a response from the API first. If Rack wants us to try to pass along to other middlewares with X-Cascade, then look for static files to serve.
