In Windows Property Sheet can have any mix of icon-less tabs and tabs
with icons.  Adds a check to see if the icon we're adding is non-NULL
(otherwise random junk from memory can be rendered) when the application
has specified the PSP_USEICONID flag is set.  Changes to the Tab control
to only render icons for tabs that have the TCIF_IMAGE flag set
(previously, if the flag was set the entire image list of icons was
rendered).
