Make system now working for build, rebuild-all, clean, pristine, distclean, clean-classes, runtests, and javadocs targets
Added a useful script for renaming packages.
Added script to compare the bytecode produced by javac with that produced by mjc.
First cut at separating mjc from JML
updated prj.el (JDE for Emacs config file) to be MultiJava specific
Tweaked build system to support extensible checks of environment variables
renaming completed for packages
Changed cygwin script to use cygpath to convert to Windows style path name. This is more robust, and I think easier to read, than using sed
