/**
* @brief UAVObjectUtilManager::saveObjectToSD Add a new object to save in the queue
* @param obj
*
* This method only tells the remote end to save the object to its persistent storage (flash
* usually), but does not send the object over the telemetry link beforehand. It is therefore
* up to the programmer to make sure the object is in the right state on the remote end before
* calling this method - the "SmartSave" feature in the ConfigTaskWidget does this, for instance.
*
* We need to manage a save queue, because once a save request is sent, we need to wait until we
* get an update from the remote end telling us whether the operation was successful. If we don't
* manage the queue, then we will end up sending save requests one after another and won't be able
* to monitor success or failure at all.
*
* The objectPersistence UAVObject works as follows:
* - Set the ObjecID and InstanceID for the target object
* - Set the operation ('save' for instance)
* - Then update the object, which sends it over the telemetry link
* - Once the objectPersistence UAVO is updated, the board will in turn update it again,
* once the operation is completed. We need therefore to listen to updates on the objectPersistence
* object, and check the "Operation" field, which should be set to "completed", or "error".
