add some const-references and as_ref when building some function types to avoid errors with impossible by-value alignment with MSVC12, issue #689
arrayfun must not construct function types with native by value + demo fixes
don't create symbolic links on Windows unless building NT2 itself + ensure CMAKE_STATIC_LIBRARY_PREFIX is also set correctly when building outside of NT2
fix unmatched signed/unsigned comparisons in demo
give more helpful messages if Git wasn't found since Git is now required to compute version
restore /EHsc on MSVC when invoking sub-projects like demo
re-preprocess specific/common.hpp + re-detect WAVE_EXECUTABLE if needed
