Battle Pass Challenges

[Tustin]

I just pushed a new commit to support challenges but I wasn't able to test them with the battle pass challenges as I don't own the battle pass. If someone who has it could test out the challenges and make sure they work, that would be great! Just post a reply stating if it works or not. Mostly just want to make sure you don't run into any parse errors with the Challenges class and also that getWeekly() and getWeeklys() work fine.

Thanks!
