- Apply a "shouldShutdownWorker"-check in "ScheduledTasks.handleNewAssignments()", when there was a "connection-error" in the previous request. This makes sure that the Worker will honor the user's shut down request, even if it's "stuck" in a connection-error loop. 

- Optimize the input-streams creation in the "FullTextsController".
