iOS: Preference Syncing

[samuelclay]

Note that this only applies to preference syncing between iOS and Android clients and NOT with the web. People have different web preferences, so we should respect that. However, I would like all iOS and Android clients (phone and tablet) to use the same preferences with an option to turn off preference syncing.

I believe we can do this with iCloud, so we don't need to involve the server.

If you want to sync preferences between Macs, iPads, and iPhones, but not also with Androids, then yes, we could do that with iCloud. If you want Android to sync with Apple devices, we'll have to use the server. (That would also have other challenges, since the preferences are likely called different things.)

I'm ok with just on Apple devices. As I wrote the ticket I realized syncing between both ios and android would have to involve the server, so let's just stick with Apple.
