I've removed the hopeful note about a future higher-level module since
it's been in there for quite a long time and nothing of the sort has
come up. There are a few places where markup was added to cross-reference
other sections, and many of the external links have been removed and now
point to newly created sections containing previously undocumented
information.
The Value Types section was created and it's contents were taken from
a function-specific area, since it applies to more than just that
function. It fits in better with the other newly documented constants.
*ReflectionKey functions used to not be documented or tested, but they are
now sufficiently documented and tested on platforms where they apply.
Additionally, fixed a bug in QueryReflectionKey which was returning an
incorrect value.
All tests pass from XP through Windows 7, on 32 and 64-bit platforms.
