Fix marshalling of std::wstring parameters in directors

Browse source 
std::wstring parameters on SWIG directors were being truncated to a single character due to marshalling inconsistencies.
This patch applies the same MarshalAs(UnmanagedType.LPWStr) attribute to director delegate methods and allows std::wstrings to be successfully received in the C# code via director calls.
