Cant get netty to flush the buffer...
Merge branch 'develop' into topic/nettyrework
Working better.

Can do chunked and normal results now.
May have chunked bodies working, but not sure.
Small changes to iteratees
Fixed the chunked problem.
Http 1.0 doesnt support chunked requests, and so you must just send and then disconnect.
TODO: seems that netty is slugish when picking up new connections. Maybe there is a setting?
Some cleanup
Changed netty to implement the upstream handler instead of the simple upstream handler.
little cleanup
