Bug 366
Minor formatting changes, no change to logic
Minor changes to SUG13 agenda
Fix step id in job file when there are missing steps.

My patch for 366 still has a bug in that the step number in the
job file is incorrect.
Bug 368
Add support for partition DenyGroups filter
Flesh out support for DenyGroups partition configuration parameter

The AllowGroups and DenyGroups configuration parameters only apply
to the effective group ID of the job. Previously any user with
access to any allowed group was permitted to use the partition.
