MSVC: Suppress unsafe template usage warnings

c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\INCLUDE\algorithm(1119) : warning C4996: 'std::_Transform1': Function call with parameters that may be unsafe - this call relies on the caller to check that the passed values are correct. To disable this warning, use -D_SCL_SECURE_NO_WARNINGS. See documentation on how to use Visual C++ 'Checked Iterators'
