fixed: Stream details for current file were not stored when item was not in the db yet
changed: Instead of only getting the playcounts, get all file info. This eg. fixes fetching media flags for non-db items and possibly other issues due to incomplete infotag
fixed: Media flags didn't load for non-db items
changed: Don't load stream details in the thumbloader thread. Fixes weird behavior caused by other threads (eg. CApp) racing when checking/updating streamdetails. Also improve thumbloader performance since not every item with streamdetails needs to be invalidated anymore
