Added macro BOOST_NO_CXX11_FINAL
We don't need to check for Apple if we've already tested that this is in MSVC emulation mode.
Change detection logic for optional feature BOOST_HAS_PRAGMA_DETECT_MISSMATCH to match the way we've done these in the past.
Merge branch 'final' of https://github.com/K-ballo/config into develop
Set BOOST_NO_CXX11_FINAL for all obsolete compilers, or for those we can't test locally.
Improve tests for BOOST_NO_CXX11_FINAL.
