Bump version number to 2.0.1. Add ChangeLog summary for version 2.0.1.libsigc++-2.0.1

2004-04-27  Martin Schulze  <mschulze@cvs.gnome.org>

        * configure.ac: Bump version number to 2.0.1.
        * NEWS: Add ChangeLog summary for version 2.0.1.
        * sigc++/adaptors/lambda/macros/base.h.m4: Fixed documentation.
        * sigc++/adaptors/macros/bind.h.m4: Hide work-arounds from doxygen.
        * scripts/cxx.m4, sigc++config.h.in, configure.ac,
        sigc++/adaptors/macros/bind.h.m4: Removed configure     check. It
        showed that the Apple gcc can also compile the sophisticated version
        of the work-around.
