[jQuery] Joern's autocomplete plugin with jquery 1.2

[tlphipps]

Hopefully this will help someone...

I noticed that Joern's autocomplete plugin uses the .eq() function
which was deprecated and removed in jQuery 1.2.  I was able to replace
the .eq() calls with .slice() calls and get things running.  Hope this
helps somebody else.

Here are the two locations to change:
Line 658:
Original: listItems.removeClass().eq(active).addClass(CLASSES.ACTIVE);
Updated:
listItems.removeClass().slice(active-1,active).addClass(CLASSES.ACTIVE);

Line 690:
Original: listItems.eq(0).addClass(CLASSES.ACTIVE);
Updated: listItems.slice(0,1).addClass(CLASSES.ACTIVE);
