Fixed MOB-426: Refactor CopyService: Apply new pattern to existing policy handlers

Fallout:
1. Policy handling for 'onCopy' has been changed to 'getCopyCallback'
2. All existing policy usage was refactored to control behaviour more closely
3. The default child association behaviour has changed:
3.1 Types and aspects control their own child association behaviour
3.2 cm:folder recurses into primary children, but merely copies the secondary association
3.3 cm:rule recurses into primary children
3.4 unless behaviour is defined for a child association, there is no recursion or copying
4. Node association behavior has changed
4.1 There is no copying of node associations.  Each type and aspect must handle this by
    recording nodes and fixing up the required associations in the onCopyComplete.
4.2 If there is a requirement, this can be added to the callback later

See 'org.alfresco.repo.copy.AbstractCopyBehaviourCallback' and derived classes for examples.

Areas to test with particular attention:
1. Normal copy behaviour
2. Copy of documents with discussions
3. Check-in check-out
4. Check-in, check-out of documents where a discussion was added to working copy
5. Copies of documents with thumbnails
6. Copies of documents with rules
7. Copying of hierarchies that contain rules to copy to another location within the hierarchy
8. Copying into folders where named children already exist
