That is done through the CGI files. That little line of links is spread out in about a half dozen places throughout them. As such, it's a bit hard to tell you how to do it exactly. The files you should need are Ultimate.cgi, ubb_library2.pl, forumdisplay.cgi, ubbmisc.cgi (maybe), and ubb_library.pl (maybe). Just search for the link titles inside those files. You will be able to see where it creates the links (should be something like $RegisterLink $SearchLink etc.), and you can just move those variables down to where you want them. Hope this helps.
