Fixes memory leaks in SC.ListView and SC.CollectionView. Since these views add observers to their related objects, they need to also properly remove those observers again when the views themselves are destroyed. Otherwise, when collection views are removed, the observers on the related objects become stranded.
Updates to latest version of jQuery, 1.11.1. Notably, there was a serious memory leak in jQuery 1.8 where the tokenCache grew continuously (because keys in the cache have a " " appended to them and the code tried to delete keys without taking the " " into account).
