Added async_io_dispatcher_base::op_from_scheduled_id().

Temporary hack around SFINAE problems with variadic template resolution in VS2013.

Improvements to find in files afio example.
Finally figured out a way around the variadic template SFINAE failure on VS2013. It turns out the really obvious simple solution was the right one, sigh.
Added missing chrono convenience types into our namespace map.

Tried turning off the ASIO race condition hack to see what happens.

Fixed a bug where AFIO was setting sequential and random access flags on directory opens (caused NT kernel to barf).

Fixed a bug where with 4Kb direct i/o if the file wasn't exactly a 4Kb multiple long the completion wakeup was being lost.

find in files for AFIO is finished, and I'm slowly fixing performance issues.
Added more to quick start.
