Title: Removes deprecated label wrapping behavior of Ember.Checkbox

in cleaning up runtime template compilations, 9fce04129121884c522a887dc57fe0c6d5bbb2c2 effectively removed Ember.Checkbox label-wrapping behavior. This removes the rest of the deprecated code related to that and updates the documentation to remove references to the old behavior.
