Complete rewrite of the cobcd script.  This incorporates Simon Sobisch's suggestion of using the
cobc -### option to create templates for execution of the various cobcd steps.  The result is greater,
perhaps even complete, flexibility in passing parameters to cobcd.  For instance, the COBOL source
file can now have any name at all (no spaces or quotes, lest chaos reign), likewise a -o executable
target can be specified as well.
