It's not possible to always disable JCheckBox animation by default

Due to this lines in WebCheckBoxUI:

```
protected boolean isAnimatedByDefault ()
    {
        // Workaround for Jide tristate checkbox
        return !ReflectUtils.containsInClassOrSuperclassName ( checkBox.getClass (), "com.jidesoft.swing.TristateCheckBox" );
    }
```

the constant

```
WebCheckBoxStyle.animated = false;
```

is always ignored.
