Proxy Object override methods

[adrian.brock]

I've fixed a problem whether the proxy factory wasn't implement equals/hashCode/toString
properly when you used java.lang.Object as the parent.

The changes can be most easily seen from the new methods in the ProxyTemplate code

 public boolean equals(Object obj)
 {
 if (delegate != null)
 {
 if (obj != null && obj instanceof Delegate)
 obj = ((Delegate) obj).getDelegate();
 return delegate.equals(obj);
 }
 else
 return super.equals(obj);
 }

 public int hashCode()
 {
 if (delegate != null)
 return delegate.hashCode();
 else
 return super.hashCode();
 }

 public String toString()
 {
 if (delegate != null)
 return delegate.toString();
 else
 return super.toString();
 }
