Upgrading to HTTP/2 draft 14 HTTP/1.x message flow

Motivation:

HTTP/2 draft 14 came out a couple of weeks ago and we need to keep up
with the spec.

Modifications:

-Allow informational type messages to be sent up the pipeline immediatley.
-Corrections to HttpObject comparitors to support test cases
-New test cases to support sending headers immediatley
-Bug fixes cleaned up to ensure the message flow is terminated properly

Result:
Netty HTTP/2 to HTTP/1.x translation layer will support the HTTP/2 draft message flow.
On the same vein as the previous comment I would like to try to keep the flow request/response agnostic.  After reading the previous comment let me know if you still want me to change.
