Get new uproxy-networking code into uproxy freedom module

Get new uproxy-networking code into uproxy freedom module.  Now we can load the chrome app + extension and have the uProxy module load, with SocksToRtc and RtcToNet objects available, along with the Google Social Provider and Storage.  Proxying still needs to be tested and there are still issues logging into GTalk that will be addressed in later pull requests.

Tested by re-running "grunt test"
Eventually we will either come up with a better way to represent these grunt tasks which include all these dependencies, or this will be simplified when we merge all the repos (#372).
