Add season_number column

[BlackYps]

During review of the client ui code we noticed that having the number of the season explicitly stored makes internationalization a lot easier.

The placement games column was added earlier, but hadn't added it to the test data yet.

With this are the name keys still going to have the .# at the end of them or will that be removed?

[BlackYps]

They will still have the number at the end. This makes every name key unique. Now that I think about it I am not sure if it is necessary to have unique name keys...

[Sheikah45]

Yes because it is this fact that would cause the name key bloat in the client i18n file. If every season just wants to be translated as {descriptor} season {#} then they really only need a key for the descriptor. Which reduces the number of variables we need and makes it easier so that every season release doesn't need a client release
