CppUnit - C++ port of JUnit Code

Update version to 1.6.1.
Add notes on SourceForge release process for CppUnit.
Tweak a few other docs.

* example/cppunittest/TestCaller.*: remove some memory leaks.
TestCaller exception catching features is now tested correctly.
Previous test tested nothing!

This commit was manufactured by cvs2svn to create tag 'REL_1_6_0'.

Final touch-ups for release 1.6.0.

* include/cppunit/TestAssert.h : changed header order to remove warning on VC++

* include/cppunit/TestCaller.h : bugfix: threw 'new Exception'
instead of 'Exception'.

Polishing for 1.6.0 release.

* include/cppunit/TestFailure.h : made destructor virtual.

* INSTALL-WIN32.txt : added some more infos about DSPlugIn.

* src/msvc6/DSPlugIn/DSPlugIn.rgs: added some registry data
that where missing to register the COM object.

* src/msvc6/DSPlugIn/DSPlugIn.rc: updated some dll version info.

* src/msvc6/DSPlugIn/DSPlugIn.dsp: fixed the custom build step to
register the DLL using regsvr32.exe. Added a post-build step to
copy the dll to the lib/ directory. This prevent a blocking
compilation error if the DLL is in use by VC++.

Correct rule to change line endings for INSTALL-WIN32.txt.

Improved strstream detection to use header <strstream>, if available.

* examples/cppunittest/makefile.am : added TestSetupTest.(cpp/h)

* examples/examples.dsw: removed some unnecessary dependencies.

* examples/msvc6/HostApp/HostApp.dsp: fixed release configuration

* src/msvc6/DSPlugIn/DSPlugIn.dsp: fixed release configuration, and
disabled the custom build command that does not work.

* include/cppunit/extensions/HelperMacros.h: reordered header to remove
some warning with VC++.

* INSTALL-WIN32.txt : detailed what was in each project. Added a FAQ
about the failing test case in cppunittest.
