make importoldchangelog plugin more user friendly

The plugin places all the changelog lines into the recent changes cache.
Truncating this cache is left to the code that normally trims the recent
changes cache. $conf['recent_days'] defines the maximum age of changes to
be considered "recent". If no changes are "recent" the changelog cache
trimmer will leave some stale changes in the cache to avoid emptying it
completely.
