Add Cupertino Settings

[matthinc]

I created an iOS-like settings layout because I think it's really missing in Flutter.

Thank you for the submission, I put this on curration watch list.
Plz Come back when you've completed more of your nice roadmap.

I would also put this under the Templates section as it's more of a full functional Page than a single Component.

I've moved Templates as a root section and added your submission to it.
