Ahh, I guess we're just setting the current working directory so that you can import
things but we still don't include the standard lib in the path.  So the "." part is reasonable
now but we're picking up Lib/DLLs from where we have our RemoteScriptFactory
class.

We probably need to figure out where ipy.exe is installed and call SetSearchPaths
on the remote script engine in RemotePythonVsEvaluator.Initialize.  

PythonRuntimeHost.GetPythonInstallDir() already has the code for finding IronPython
so it should be pretty easy to fix if anyone wants to give it a try.
