added search to forums. oracle version using intermedia, postgres versionsimply using like statements for now. forums-search-create.sql andforums-search-drop.sql aren't sourced automatically since they require manualloading (must switch schema user at certain points) please follow theinstructions in the file. need to figure out a good way to do this.
the package is 99% ported to oracle. the only file that still requires alittle porting is www/search.tclnow all someone needs to do is write the FtsEngineDriver for Oracle. i didn'tdo it since i didn't need site-wide-search quite yet.
added dotlrn_graphics_url var so that the graphics can go in a dir that everyone can read [server_page_root]/graphics. users have to create and copy the dotlrn gifs to this dir. this may not be the long-term solution to this problem, but it's a workaround.
