Whoops missing semicolons.
Changed op dispatch logic in chain_async_op to be identical to complete_async_op. Hopefully fixes that unit test regression.
Added new intermediate quick start example.
Fixed another very subtle race condition. This hopefully gets all green on the CI.

Also the test runner now observes BOOST_AFIO_NEED_CURRENT_EXCEPTION_HACK, and I turned BOOST_AFIO_NEED_CURRENT_EXCEPTION_HACK on for all older C++ 11 compilers rather than just VS2010.
Fixed the TabsToSpaces script not fixing up .ipp files.
