WP_Screen::add_help_tab() public WP 3.3.0

Add a help tab to the contextual help for the screen.

Call this on the load-$pagenow hook for the relevant screen, or fetch the $current_screen object, or use get_current_screen() and then call the method from the object.

You may need to filter $current_screen using an if or switch statement to prevent new help tabs from being added to ALL admin screens.
