1. Added long options to condor_submit_workers to match those in the work_queue_worker.
2. Updated the man page and the help message to reflect the changes.

1. I removed the -c option in condor_submit_workers, which was added by Dinesh for the --cores options.
2. long options using equal signs won't work in condor_submit_workers, e.g.: --timeout=30. A valid one would be: --timeout 30.

Parrot's process group).

Fixes #44.
