iPhone app: a first screen that says exactly what to do

The app finds the Frame by itself (Valve's _steamos-devkit._tcp Bonjour
service, else the saved address or frame.local on port 22), so setup is two
numbered steps: wake your Frame (Looking… / Found ✓, and after a few seconds
exactly what to check), then the Developer Mode password and Connect. Manual
address and key options sit under Other ways to connect.

A paired Frame that doesn't answer is almost always asleep: instead of an
error, Waiting for your Frame says how to wake it and connects as soon as its
SSH port answers (checked every 3 s; 4 s after the stand-in came back).
