Catch errors that may occur whilst receiving data from the Aphlict server.
Summary: Ref T4324. Currently, if the AphlictMaster receives dodgy data from the Aphlict server (invalid JSON, for example) then a syntax error will be thrown and the AphlictMaster will die. Instead, catch errors and raise a notification.
