Title: Bumping netty version from 3.9.2 to 4.0.21. 

Code changes are only enough to get it to compile, and everything was done with the help of the following resources:

http://netty.io/wiki/new-and-noteworthy-in-4.0.html#wiki-h3-25
http://netty.io/4.0/api/index.html
http://netty.io/3.9/api/index.html

Tests currently fail, as i suspect the server does not handle any requests, i.e. perhaps the handlers are never invoked. please consider this a draft version of the pull request and if anything jumps out at you as obviously wrong, i will gladly fix it.
