Add a help choice '?' to the yes or no prompt for quadoptions.

The prompt currently just prints "See $%s for more information." where
%s is the variable name.  This will at least give a pointer to what
variable can be adjusted to change the prompt behavior.

A handful of boolean variables also control prompt display.  Add a
help choice for those too using the function mutt_query_boolean().
