The cloud manager registers itself as an event source as a mean to be polled periodically by the GUI or engine code. The periodical polling is used to update the OSD icon indicating background sync activity. Also move the cloud icon from ConnectionManager to CloudManager, allowing to decouple icon handling from network connections updates.
