Compiled against Wicket 6.9.0 and update JQuery UI to 1.10.3

Hi, after updating to Wicket 6.9.0 most of the UI widgets doesn't work anymore because Wicket has updated JQuery to version 2 and for fallback IE8 and lower 1.9. In both versions the current (old) JQuery UI doesn't work anymore so I updated to the current stable.

I tested most of the widgets and it works, it is just tested by converting our application to the updated version.
