Passthrough data urls requests

[cdes]

This passes through data urls without raising exceptions.

Thanks!

Mirage currently ships with a couple default passthroughs, so we should probably add to that list rather than unhandled request.

I'd like the understand which passthroughs safely solve this issue. Does adding this.passthrough('data:**') in your server definition solve this? Or do we need to do an indexOf check on every request?

@ryanto: passthrough behavior does not work for some reason. That's why I needed to do what I did.

I've stumbled accross this, where the passthrough still throws excepts to specific endpoints.
