Add Display a marker in the queue view indicating a rescan

- Either using the 'Force rescan' blog option or as long as the LastId of the blog is 0, a full rescan of the blog will be performed.
- Since this can take a long time depending on the crawler and blog size, a marker ("[F]") is displayed after the blog name in the queue.
