Most subclass of views::FocusChangeListener have to implements all the methods by given empty implementations when they do not need it. This CL gives empty implementations for views::FocusChangeListener methods so that they do not have to be re-implemented by every subclass. The subclass will only have to re-implement what they need. The change in most of the files consist to remove the empty implementation from them.
