[sync] New SyncML version, database update required

[Karsten Fourmont]

Hi,

there's a new SyncML version in cvs.
The syncml map is now finally moved out of the datatree and into a 
separate sql table horde_syncml_map.

1) upgrade everything to cvs. You need current cvs versions of kronolith 
and turba as well. The datatree issue is also fixed in cvs.

2) create the sql table by running horde/scripts/sql/horde_syncml.sql

3) Do a sync. As all old mapping info is lost, the first sync will be an 
initial slow sync again. So if you use the synthesis client, you should 
do a "reload device" which deletes all data on the devide and then loads 
everything from horde. If you use a client that doesn't have this 
feature: I made fixes in kronolith and turba so that there should be no 
duplicates when doing an initial slow sync with data on the device and 
in horde as well. However for notes and tasks such a slow sync results 
in duplicates at the moment.

Sorry for the inconvenience, but this was really necessary. Performance 
should be greatly improved with the new table.

Cheers,
  Karsten
