Added first backend processing for retrieving all queued searches. This should fix the frondend blocking when doing manual searches for episodes, because the backend is free sooner. It now only queues the search.

For the getManualSearchStatus() function, only use curItem from the ManualSearchQueueItem or FailedQueueItem threads.
