`$.cleanData` is always overridden (jQuery UI detection does not work)

[victor-homyakov]

At https://github.com/medialize/jQuery-contextMenu/blob/master/src/jquery.contextMenu.js#L47 you are trying to guess when you should override original $.cleanData like jQuery UI does.

But at least with jQuery UI 1.10.X check if (!$.ui || !$.ui.widget) does not work - there is no $.ui.widget, only $.widget at https://github.com/jquery/jquery-ui/blob/master/ui/jquery.ui.widget.js#L28.

As a result, with jQuery UI 1.10 I have 3 implementations of $.cleanData:

1. From jQuery (original)
2. From jQuery UI
3. From contextMenu, the same as in 2.

This has some performance impact when deleting/replacing large DOM subtrees.
