CanJS: Consistency fix for clear button

Closure app doesn't apply 'completed' class to items

Class name is now set in the template rather than at the view layer, because
todomvc.view.ToDoItemControlRenderer#setState is called on the old element
before it's removed from the DOM, so modifications don't persist.

Update to thorax latest, fix checkbox error on empty. Fixes #411

Appended a trailing slash to the links for dermis, backbone_marionette, thorax.
