Simple shell that loads a dll and calls an entrypoint function passing in a handle to a pipe created by the shell app.

To achieve this I had to make mojo_system a <(component) so sample_app.dll could link against it. Trung, Darin tells me you had a different idea about how to achieve this. Consider this CL a starting point for the discussion :-)
