hugin updates

[Yili Zhao]

Hi,
  compiled under windows successfully, only some warnings:
  --------------------------------------------------------
  hugin/OptimizeFrame.cpp: In member function `void 
   OptimizeFrame::setOptimizeVector(const PT::OptimizeVector&)':
hugin/OptimizeFrame.cpp:281: warning: comparison between signed and unsigned 
   integer expressions
  hugin/PreviewPanel.cpp: In member function `void 
   PreviewPanel::updatePreview()':
hugin/PreviewPanel.cpp:176: warning: unused variable `bool corrLens'
  hugin/huginApp.cpp:195:18: warning: unknown escape sequence '\h'
  --------------------------------------------------------

  When I run hugin, there are some errors recorded in log.txt:
  --------------------------------------------------------
  Cannot load resources from file 'e:\project\hugin-20031006.tar\hugin\src\hugin/xrc/optimizer_edit_dialog.xrc'.
  ERROR:  (hugin/huginApp.cpp:203) OnInit(): Tempdir could not be created: c:	emphugin
  ERROR:  (hugin/huginApp.cpp:208) OnInit(): could not change to temp. dir: c:	emphugin
  --------------------------------------------------------------------------------------
  I can not find file "optimizer_edit_dialog.xrc" in corresponding directory.
  I have an idea about windows temdir: it seems that mingw32 can link win32 SDK functions, so maybe I 
can do this:
  ifdef _WIN32_
    #include <windows.h>
  endif
