Display more informative message when HtmlHelp stub is invoked

[Mike Hearn]

This one might prove a tad controversial. In some cases, like where we know
a stub would produce UI anyway, I think it's a good idea to show a helpful
message box rather than assume the user can interpret stub messages they may
not even see.

thanks -mike

Display more informative message when HtmlHelp stub is invoked,
add A/W conversion code, remove useless (and wrong) hungarian
notation from function prototypes.
