[javascript] update to jQuery 1.4.2 and jQuery-ui 1.8.5
The most notable changes are :
- A bug in jQuery 1.4.2 forces us to add 2 noop() methods
on cw objects to handle event unbinding, see :
http://dev.jquery.com/ticket/6184
for more details.
- jquery.autocomplete.js is not maintained anymore as it now has
a standard implementation in jquery ui. The downside is that
the new autocomplete version needs more work to be used.
cubicweb.widgets.js defines a cwautocomplete plugin which is
just a (not so) thin wrapper around the std autocomplete plugin
to keep backward compatibility and usage simplicty.
The original autocomplete author wrote a nice migration guide :

- If you're using jQuery.ajax directly, you might have surprises
with arguments serialization for arrays. To get the old behaviour,
you need to pass a `traditional: true` extra arguments to jQuery.ajax.
Of course, it's transparent if you're using cubicweb higher level
helpers such as loadxhtml, loadRemote, etc.
