Fix bug where loading an OAR with a deeded parcel would always set the parcel owner ID to the estate owner even if the group UUID was present.

Aims to address http://opensimulator.org/mantis/view.php?id=6355
As part of this work, an incomplete IXGroupsData was added which currently only allows store/fetch/delete of group records
(i.e. no membership data etc)
This is subject to change and currently only an in-memory storage implementation exists for regression test purposes.
