Add BroadcastItemTitleScorer to YV and Redux equiv updaters

YouView and Redux items are all single broadcast items which often
inherit their titles directly from their brands. The
BroadcastItemTitleScorer will resolve and check the title of an item's
brand if the candidate equivalent's title doesn't match. It will also
resolve and check the candidate's brand title if necessary.
