The cache should be cleared in the background

[BernhardPosselt]

The news app on the serverside clears read items which arent starred if they go over 200 entries: https://github.com/owncloud/news/blob/master/db/itemmapper.php#L250

I found myself clearing the cache manually quite frequently, i think this should be done automatically (you can set a hihger threshold or make it configurable, maybe 1000 read items?). You can clear the read items when the feeds are synced for instance

Yes, it's build in since v 0.3.8 ;) implemented it yesterday.

btw. starred items are getting cleared, too. (I think this is better for the cache) --> can be downloaded if needed by the function "download more items"
