Feature Requests: Dark mode, ladder options - ranked, no EX, and Little Cup

Freef

I'd really like dark mode. The white screens are blinding and harder on my phone battery.

I'd also really like more ladder options including:

• Ranked - Pretty self explanatory. Competitive battle ladder, ranking based on wins/losses.
• No EX - A ladder where ex pokemon are banned
• Little Cup - A ladder where the only allowed pokemon are basic pokemon capable of evolving.
