wix: add help for current internal topics

This makes the changes in a79cba6cb206 and 84784f834b3a available on Windows.

I'm not setup to make the installer, so someone with experience in this area
should probably give it a look.  In looking around to try to figure out how to
build the installer, it looks like the Makefile may need an update to $DOCFILES.
