manufacturer and the recogniced GroupDAV client as product name.
This way we are able to handle different GroupDAV clients, as we
allready do with different SyncML clients.
Also removed the no longer needed code enabling the use of the real UID,
as SyncML does no longer misuse the UID for it's GUID.
longer use GUIDs containing eGW's install_id, as the information is
irrellevant for SyncML and cause doublications of entries if the
install_id changes.
I plan to have a new rc4 Wednesday or Thursday containing these changes.
