transmitted like a common status code (fix for BB), AdditionalFolders
API and statically shared folders work always with backendids (they are
internally mapped and transmitted with integerIds), 
expose integerIds in the listing of the AdditionalFolders API as
"syncfolderid", generate integerid when an additional folder is added,
have ZPush::$addSyncFolders and
DeviceManager()->GetAdditionalUserSyncFolders() always work on
backendIds, ZPush::GetAdditionalSyncFolders() can return integerIds as
keys if requested (default as backendIds), do Backend->Setup() with
backendIds in ChangesMemoryWrapper, backendfolderid needs to be set in
SyncParameters unsetdata, allow Notes folders as additional static
folders.

- Move folders correctly with mapped and traditional profiles
- Changed IIChanges->ImportFolderChange() to return a SyncFolder object
to transport all ids.
- Added logging to Zarafa importer and folder move operations.

- Changed IImportChanges interface to use an SyncFolder object on
ImportFolderDeletion, changed all implementing classes to work with the
new parameter to allow clean rewriting of ids for backends.
- Expose folderid <-> backend-folderid conversion in both directions via
DeviceManager, saved in the ASDevice contentdata. 
- All folderids passed to the backend, are rewritten to the
backend-folderids, where all processing operations are done (as is) on
the new/short AS folderids.
- Never save ASDevice data when doing Ping, as on hierarchy changes
there will be race conditions between, e.g. FolderCreate and the running
Ping request, where Ping potentially wins writing this information (risk
of inconsistent AS folderids). The ASDevice is only changed because
during hierarchy verification new folders get a new AS folderid. This is
not used anywhere and really done on the following FolderSync operation.
