Add Golden Saucer to Weekly Challenge Log

[Kaiser-Ace]

We mentioned this in the last Letter from the Producer LIVE, but in Patch 3.1 we're adding Gold Saucer to the challenge log. You'll be able to earn from 500 to 4,000 MGP for completing these challenges, so make good use of them!

Sweet, always up for a more efficient way to make coin be it Gil or MGP. Thanks devs.
