[QGIS-Developer] Catch qgis exit

[Ujaval Gandhi]

I saw that there is a aboutToQuit signal emitted just before a QApplication
exists. The following works from QGIS Python Console.

def test():
    with open('/tmp/test.txt', 'w') as f:
        f.write('wrote while exiting')

qApp.aboutToQuit.connect(test)
