Title: Update to spdy/3.1 and ignore old spdy frames.

related to issue #354

Spdy 3.1 supports connection-level flow control, which allows you to limit bandwidth without limiting parallelism.

This implementation ignores deprecated NOOP (spdy/2) and CREDENTIALS (spdy/3) frames.

Tested via `ExternalSpdyExample` on google.ca and twitter.com
