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.
