Added methods:
void AddParam(const std::wstring & param_name, const std::wstring & param_value);
void AddParam(const wchar_t * param_name, const wchar_t * param_value);
void RemoveParam(const wchar_t * param_name);
void RemoveParam(const std::wstring & param_name);
This is only temporarily, we will be using the pt::Space structure in the future.
