Revise the ordering, headers and layout of the Audit, AuditPool etc

These are not in keeping with other similar groupings cf ProductList/Product/Intent and ResourceSet/Resource.

Firstly the Audit section should preceed ProductList and ResourceSet because that's how it is in the XJDF table.

Secondly the header AuditPool and Audit should become AuditPool (to match the XJDF entry).  I see the headings as

• 3.x AuditPool
• 3.x.1 Audit
• 3.x.2 AuditCreated
• 3.x.3 AuditNotification etc

Some rearrangement to move topics to the correct section will also be required e.g. moving the table Alignment of Audits and Messages to the Audit section. Pointing AuditPool hyper links to the new AuditPool. etc.

Some parts of the reordering also apply to JDF too.
