ZPushAdmin and WebserviceDevice. Added constant
DeviceManager::FLD_FLAGS_REPLYASUSER. Renamed private method
DeviceManager->getAdditionalSyncFolder() to
getAdditionalSyncFolderObject() for better readability, modified checks
on ASDevice->EditAdditionalFolder() to allow a flag modification
(maintaining the same name), added SyncFolder->Flag as ignored parameter
and populate it when calling
DeviceManager->GetAdditionalUserSyncFolders().
