Summary: Support for user supplied exception handler

Initial Comment:
win32ui.h
  1. Added ExceptionHandler declarations.

win32uimodule.cpp
  1. Converted Python_run_command_with_log to use
ExceptionHandler.
  2. Converted gui_print_error to use ExceptionHandler.
  3. Added TRACE to gui_print_error which warns about
recursive call.
  4. Implemented ExceptionHandler.

win32thread.cpp
  1. Converted to use ExceptionHandler.

win32virt.cpp
  1. Fixed crash if we re-enter the error handler.
     Example: Document.OnDraw raises. We show a dialog
box with
     the traceback. The dialog box being displayed in
front of
     the document will trigger on move another
WM_PAINT. This
     will trigger Document.OnDraw which will probably
raise again.
     So while being in the error handling routine, we
enter it again!
     gui_error_print is protected against this, but the
line
     will fail "char *szRepr =
PyString_AsString(obRepr);" because
     obRepr is NULL (at least on my machine).
  2. Converted to use ExceptionHandler.
