Integrate sdo-videogameseries changes (VideoGame, VideoGameSeries, Game etc.)

These include a few small areas beyond games/series, mostly cleanup of extra domainIncludes/rangeIncludes assertions. The bulk is a reworking of Series to be more independent of its TV/Radio origins so that we can have books, games, periodicals under it. We also renamed 'tip' and 'help'. The docs/releases.html will need updating to match.
