Made collections port compatible with MSVC2008

The issue was caused by the fact that in this version
of MSVC unordered_map class is defined in <unordered_map>
header file, but this file declares the class int std::tr1
namespace.

This confused existing assumption that if there's an
existing <unordered_map> file then class is declared
in std namespace.

Added an extra check to CMake which detects whether
it's std or std::tr1 which actually contains class
of unordered_map.

This might be changed/cleaned in the future, for
now committing to our repository to solve compilation
error on windows.
