* Created a new wxObject method: wxObject::CopyObject(wxObject&)

* Created a new wxObject method: wxObject::CopyObject(wxObject&)
  and wxObject::Clone() uses it.
* Added some CopyObject to events.
* Reenable the idle loop in wxEvtHandler::ProcessThreadEvent(...)
* Some correctness in wxSocket.
   Major bugs remaining:
      - it seems there is a mutex problem when it works too quickly
      - all threads aren't destroyed ...
