		Does a custom tab need to be highlighted?
        Since users can have custom tabs we need to highlight them when the page is
        accessed.  However, when we do, we need to prevent any of the default tabs
        from being highlighted.  Say, for example, that someone creates a tab pointing
        to the Photo Gallery.  When that tab is accessed it needs to be highlighted (obviously)
        but we don't want the MODULES tab to also be highlighted or it'll look funny.
        Since the Photo Gallery is within the MODULES tab it'll hightlight itself automatically.
        So... we'll use a variable called:  $highlight_override
        When set to TRUE, this variable turns off all default tabs.
        The following code blasts thorough the GET variables to see if we have
        a custom tab to show.  If we do, we'll highlight it, and turn off
        all the other tabs.
