  - Fix for defect of combo box and popup menu on Mac OS X

The cause of the defect seems to be some problem in loading of Substance look and feel. (What I've tried: Commenting out the "setLookAndFeel();" in Application.java fixed the problem, but UI became ugly. Specifying LightZoneLookAndFeel fixed both of them.)

  - Updated Quaqua LaF to version 8.0
