GameDB: Updating genres (#3315)

* Updating genres

Changed "Sports / " to "Sports -"  , as / should indicate multiple genres and - subgenres (there's still more to do).
Also added a ** DEMO ** genre as it's nice to be able sort them out.
Done a bit of work on the Lightspan educational games - but haven't completed as I've lsot the will to live with them.
Also done other clean ups on genres like cases and trailing dots.
