Made scripts a little more consistent, they should now work with IBM's

JDK on AIX out of the box.

Ant will now prepend CLASSPATH to the jars in ANT_HOME/lib like it
always did for Windows - if this is not the correct order, change it
here and in the batch file. We need to be consistent.

Make sure :: doesn't slip into the CLASSPATH when adding the library
jars.
