CppUnit - C++ port of JUnit Code

* src/msvc6/testrunner/TestRunner.dsw: added DSPlugIn.dsp. TestRunner
depends on DSPlugIn.

* src/msvc6/testrunner/TestRunner.cpp:
* src/msvc6/testrunner/TestRunnerDlg.h:
* src/msvc6/testrunner/TestRunnerDlg.cpp:
* src/msvc6/testrunner/MsDevCallerListCtrl.cpp:
* src/msvc6/testrunner/MsDevCallerListCtrl.h:
* src/msvc6/DSPlugIn/*: integrated patch from
Patrick Berny (PPBerny@...). An add-ins for VC++. Double-cliking
a failed test in the TestRunner, VC++ will open the source file and
go to the failure location.

* src/cppunit/Exception.cpp:
* include/cppunit/Exception.h: compile fix, call to overrided
operator = of parent class failed. Using typedef to the parent
class fix that.

* src/cppunit/cppunit.dsp: added TestFixture.h

* src/cppunit/TestFactoryRegistry.cpp: removed <utility> which isn't
needed any more.

* include/cppunit/TestCase.h:
* include/cppunit/TestSuite.h:
* include/cppunit/extensions/TestFactoryRegistry.h: added
include <Portability.h> before any other includes to remove warning
with VC++.

* include/cppunit/Portability.h: moved platform specific includes at
the beginning of the header. fixed CPPUNIT_HAVE_CPP_SOURCE_ANNOTATION
declaration.

* include/cppunit/config-msvc6.h: removed pragma once (useless, should
be put in each header to have an effect).
