Summary: JFreeChart not added as a TitleChangeListener in some cases

Initial Comment:
The problem occurs when JFreeChart is created with constructor parameter title set to null.

In this case, a TextTitle is not created and so the line "this.title.addChangeListener(this);" in the constructor is not called.

But if later, we call JFreeChart.setTitle(String) which calls JFreeChart.setTitle(TextTitle title), the JfreeChart is not added as a change listener :
"
public void setTitle(TextTitle title) {
        this.title = title;
        fireChartChanged();
}
"

As a result, no ChartChangeEvent is sent when title is modified.

Good spot.  I have a fix (and corresponding test case) that I'll commit to
SVN in a moment.
