iOS: the app's settings in Settings, not behind a shake; iPhone upright (#445)

The server address and the player token were set from alerts that
opened on shaking the phone, which nobody finds. Settings now has a This
device section in the app: the server, the player token and its
address, and a Make button that creates an API token and hands it
straight to the app's keychain. The app sends what it has at ready
(appSettings) and takes setServer, setToken and clearToken; a new
server rebuilds the web view as the alert did. The first-launch prompt
and the Cannot reach alert stay native, since there is no page then.

The iPhone is portrait only; the iPad keeps all four orientations, which
Split View and Slide Over need (#434 checked the iPad's layout).

Build 14.
