Vadim Zeitlin 04ca40fce8 Destroy modeless wxGenericAboutDialog when it is closed.
Don't leave the wxGenericAboutDialog object alive when non-modal about dialog
(as can be used under GTK and OS X) is closed. This is wasteful and, worse,
resulted in the program not exiting after such a dialog was shown because it
counted as a remaining open top level window.

This also fixes the same bug in wxGTK when using GTK+ 2.4.
