Refactored Arp into ArpAttributes - single attribute on Entityrevision and deleted all GUI related ARP stuff. Needs to be rebuild in the editentity new ARP tab
History tab is now after the ARP tab
The EntityRevision is still loaded by plain sql, but stored by Doctrine. This gave problems for the arp_attributes that need to serialized manually because Doctrine is not - yet - responsible for loading the RevisionEntity
Added NULL array for empty ARP
WIP for moving the ARP to the SP editentity page
Commit before - WIP - merging into ORM branche
