RELEASE: v2.0.4

[Warren Young]

If you aren't having troubles with MySQL++, you can ignore this release. 
  Just minor bugfixes and cleanups.

     o Made mysql_shutdown() second parameter autoconf check less
       sensitive to compiler pedantry.

     o VC++ library Makefile is now smart enough to re-create the
       import library, if it is deleted while leaving the DLL alone.

     o Added libmysqlclient.def to tarball.

     o Reworked most of the top-level README* files.

     o Renamed LGPL file to LICENSE.
