Widgets title improvement

[alexvorn2]

we have now:

$title = apply_filters( 'widget_title', empty( $instance['title'] ) ? __( 'Categories' ) : $instance['title'], $instance, $this->id_base );

why not to use?

$title = apply_filters( 'widget_title', empty( $instance['title'] ) ? $this->name : $instance['title'], $instance, $this->id_base );

Because widget name isn't the same as the the widget title, even they have the same values.
