After creating a game, leave several of the default values on the form the same, to make multiple entries faster.
Added created_at to game properties, so we know which game was most recently created.

This will allow us to default to values from a user's most recently created game when visiting the site.
When loading the page, set default values for some of the game fields to the same as the previously created game.
