Serialization of null and void values is broken

[GoogleCodeExporter]

Null values (and void, I think, too) do not serialize/deserialize correctly. To 
demonstrate, run this code (in Java, not beanshell):
        Interpreter origInterpreter = new Interpreter();
        origInterpreter.eval("myNull = null;");
        ByteArrayOutputStream byteOS = new ByteArrayOutputStream();
        new ObjectOutputStream(byteOS).writeObject(origInterpreter);
        Interpreter serInterperter = (Interpreter)new ObjectInputStream(
                new ByteArrayInputStream(byteOS.toByteArray())).readObject();
        System.out.println("Expected " + origInterpreter.eval("myNull")
                + ", but got " + serInterperter.eval("myNull"));
        System.out.println("Expected " + origInterpreter.eval("myNull == null")
                + ", but got " + serInterperter.eval("myNull == null"));     

The expected output is:
Expected null, got null
Expected true, got true

Instead, the result is:
Expected null, got bsh.Primitive$Special@169e11
Expected true, got false

This patch should fix the problem and adds a junit test to verify.
