Subject: [PATCH] Add Prelude comment to Java Output files

Add a comment to the head of every Java output file stating that this file was
produced by CS2J.

A command line argument (markDate) controls  whether the translation date is
included in this initial comment.

markDate should be set false for Rustici (end similar) else it will
produce spurious source control diffs
