#1744

• added the new Hive engine. The engine can now be executed in the Hive. If child tasks are created it pauses and is transfered back to the server. If the child tasks are finished it is sent back to a slave.
• changed the server so that it reschedules paused parent tasks if their childs are finished as well as tasks where FinishWhenChildJobsFinished is set to false
