Modified Zeo sleep graph to align start time to the previous 5 minute boundary.  The datastore directories for existing zeo instances (dev.kvs/<guestId>/Zeo) should be moved aside and the zeo data re-exported to the datastore.  This can be done with curl:   curl -u <adminUsername>:<passwd> -X POST 'http://localhost:8080/api/bodytrack/uploadHistory?username=<guestUsername>&connectorName=zeo'
