* reverted Adi's premature changes to BWindow and restored _DetermineTarget() and

task_looper() again.
* removed BMessenger::fPreferred - whenever you had to specify "usePreferred" separately,
  you don't have to do that anymore - use B_PREFERRED_TOKEN instead.
* fixed BTokenSpace::GetToken() semantics: it will no longer touch the "object" argument
  in case of failure.
* Introduced a BWindow::_DistributeMessage() that will be part of the event dispatcher
  counterpart to the app_server (the other will be _DetermineTarget()).
* Made it easier to use Michael's Message4 implementation: just add the following line
  to your UserBuildConfig:
	AppendToConfigVar DEFINES : HAIKU_TOP src : USING_MESSAGE4 : global ;
* Introduced ServerWindow::HandlerMessenger() and FocusMessenger() - the first will
  target the client handler, while the other will target the preferred handler of the
  client looper (usually the view having focus).
* Fixed dano message unflattening in the Message4 code.
* Changed BMessage::PrintToStream() to no longer use macros in the Message4 implementation.
* I hope that's all - it's a huge change, but it's all connected.
