HTML_QuickForm_Liveseach draft update

Hi all, finally i updated this proposal to work with HTML_AJAX http://pear.php.net/pepr/pepr-proposal-show.php?id=308

@todo    Make the style variable as class, so the user can choose it before instatiate the element
@todo     Make HTML_AJAX_Queue_Interval_SingleBuffer variable

In the example page you can see the old version too (not dependent from HTMl_AJAX) so you can see differences. It's for me very useful to read comment and advices about it to make it better. P.S. to HTML_AJAX developer: some advice to make the javascript part of this code more..."elegant" ? ;) Thanks in advance Giuseppe Dessì
