Better handling / localization of GameInfo

The GameInfo tag uses an unused variable in Stardew Valley's code that is set by the game, not by my mod. My plan is to allow the values to be localized by parsing the string into translation keys. We could also use this to add spaces to the nap names or to provide better map names. For example:

• At BusStop -> gameInfo.At-BusStop -> At the Bus Stop
• At SeedShop -> gameInfo.At-SeedShop -> At Pierre's General Store

This could also be used to improve the Location tag.
