• add an optional expand parameter to REST group search: "attributes"
• syncing attributes will be any attribute with a name starting with "synch."
• on full synchronisation of a Remote Crowd directory, ensure that all group attributes beginning with "synch." are made to reflect the remote directory
  • any that exist internally, but not in the remote will be removed
  • any that don't exist internally, but do in the remove will be added
  • any that have differing values will be updated to the remote value
• on incremental synchronisation of a Remote Crowd directory, apply any changes to group attributes beginning with "synch."
• only Remote Crowd directories will sync group attributes
• this does not apply to User attributes
• this does not apply to attributes that do not start with "synch."

This feature is so that we can make meaningful changes to groups within the parent Crowd that can be reflected in the child applications.
