Get the SimpleApp in WinRT working against MVC 4 and MVC 5 (Web API) host implementations.
#269 Initial implementation of brokered data portal channel.
#269 Change the .NET host to implement an async pattern and change the WinRT proxy to use simple async/await to invoke the data portal.
#269 Throw an exception if the caller tries to set isSync to true. The proxy will not support synchronous client calls, which should be no problem in a WinRT client.
#269 Separate the host (brokered assembly) from the actual brokered data portal host implementation to allow full use of .NET in the data portal implementation.

Update brokered proxy to match the behavior of HttpProxy in most respects.
