11010	Fix memory leaks caused by CKEDITOR.filter.instances storing nested editables' filters forever	Piotrek Koszuliński		"Every nested editable which has allowed content rules defined has its filter instance. These instances are stored in nested editable instances, which most likely are correctly garbage collected. But filter instances are also stored in CKEDITOR.filter.instances and they are kept there forever.

We could have filter.destroy() method removing instance from the instances hash and doing other cleanup if necessary. Then we could destroy filters when destroying widgets."	Bug	confirmed	Normal		UI : Widgets	4.3
