Added queued.png image.. for manual searching
Fixed issue where consecutive manual searches where not queued properly
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.
Created a returning ajax call for getting a list of all searches in queue en running on the displayShow page.
For the getManualSearchStatus() function, only use curItem from the ManualSearchQueueItem or FailedQueueItem threads.
