/* 20 Aug 2006: This started off as actb.js from
   http://www.codeproject.com/jscript/jsactb.asp.
   
   But it didn't work without the addEvent stuff that was in the demo
   page.  Web browsing suggests that this widely distributed stuff is
   from another source.  There is a warning about it at quirksmode,
   but I think I should be immune from it.  So that was added at the
   top.
   
   Then I hacked in a hook to do server lookups.  This is the code that uses my
   new actb_lastdownload variable.

   Then I wrote the download code.  This is a combination of the demo
   at http://www.w3schools.com/xml/tryit.asp?filename=try_xmlhttprequest_js1
   (although modified to move the state change function into a closure)
   and the "explode" function from http://textsnippets.com/

   This makes it a huge bag of code with mixed copyrights.  I'm comfortable
   saying that the creative commons license that applies to the original actb
   code can be taken as applying to this derivative work, but if you wanted to
   use this in something that costs real money, you'd better check with your
   lawyers
   
   1 Sept 2006 - I noticed a mountain of errors from the Firefox CSS Parser.
   Changing the "=" to ":" in actb_hStyle prevented this, and made the
   highlighted part bold as well!
   
   1 Sept 2006 - added a default of "sans-serif" to the "arial narrow" font
   family, for those of us who don't have arial.
   
   4 Nov 2006 - made "tab" leave the box without selection: much more how I'd
   like it to work
   
   August 2008 - changed the format to work better with names coming from SQL

   April 2009 - fixed (in a messy way) a bug where the top element didn't
   show in some browsers

   June 2009 - Added UTF8 accented character folding - so each entry has
   a "disp"lay and a "match" version
