Bugfix :: searchForNeededEpisodes : Fixed NoneType AttributeError exception.
Don't store None value bestResult (occurs when all results are rejected) in foundResults list. Quality comparisons with results from other providers throws an exception.
* Added new .ini only variable **anon_redirect** with the default set to `http://derefer.me/?`.

What this does is prevents your local SB install from appearing in the backlink statistics of another web-page.
There are a whole bunch of link protection / anonymizers out there, just make sure you use the proper URL (ends with ?) if you change the default.
Add html5 attribute ```rel="noreferrer"``` to the anon links as well just to be even more 'secure' on not leaking the referring source.
