Updated Game Table

I updated this table of Combinatorial games and some of their known properties. This time I added a column to list variants of games. I still want to add more games and properties, please inform me of more results to add! These could include:

More Games! I'd love to add more rows.

Properties! I'm sure there are some incomplete cells that could be updated. This time I added "Open" if the problem is known to be open (there must be more of these).

References! I added a bunch of links, but there must be more (or better) supporting documentation for some things. I would love to add more links.
