Put the renamer as a function of a download status checker in the searcher class

The changed functionality is as follows:
- the renamer is not on scheduled interval anymore
- the download status checker checks the status of all snatched releases every x minutes
- if a release has downloaded it fires up the renamer (if enabled)
- if it failed, it sets the release to ignored and snatches the next best release

With these additions the renamer wont scan your hd anymore when it is not required, and will retry failed downloads with new releases.

To do:
- the only downloader implemented is SabNZBd, for the others it defaults to the old behavior when releases are snatched (I think!?)
- a button to scan manually: Items added to the renamer folder are only picked up after a download completed
