Filtering out data items added by angular from options object because too deep for kendo's deepCopyOne.
Added filter function to do so and using it to get the list of widgets from jQuery.fn.
Had to upgrade angular to 1.0.5 due to bug with 1.0.4's forEach and array-like objects: https://github.com/angular/angular.js/commit/ec54712ff3dab1ade44f94fa82d67edeffa79a1d#src/Angular.js
