Thin client wrappers and custom transport messaging example

https://github.com/andrewgrant/RemoteSession:

• A plugin for Unreal that allows one instance to act as a thin-client (rendering and input) to a second instance
• Shows how to capture the render target framedata (using FFrameGrabber) asynchronously

https://github.com/andrewgrant/BackChannel:

• BackChannel is an experimetal plugin that allows external tools and apps to query for and push data into a running Unreal session.
• The goal is to support 2-3 ubiquitous protocols where implementations can be easily created or found for popular languages. The short term focus is OSC over TCP/IP and JSON REST over HTTP.
