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.
This is done in the way that one would expect (e.g. moving a folder increments version number on both source and destination parent folders).
This should hopefully improve viewer reuse of its cached inventory information.
Currently MySQL only but will be implement for SQLite/MSSQL if there are no issues.
This prevented more than one additional ordinary folder from being created in the base "My Inventory" user folder.
Added regression test for this case.
Switched tests to use XInventoryService with mostly implemented TestXInventoryDataPlugin rather than InventoryService
Disabled TestLoadIarV0_1SameNameCreator() since this has not been working for a very long time (ever since XInventoryService) started being used
since it doesnt' preserve creator data in the same way as InventoryService did and so effectively lost the OSPAs.
However, nobody noticed/complained about this issue and OSPAs have been superseded by HG like creator information via the --home save oar/iar switch.
