connect.sh and frame_connect.py now try Valve's steamos-devkit-service
first: GET /properties.json for the login user, then POST /register with
a new RSA key (~/.ssh/id_rsa_frame_devkit, the only type it accepts), so
the user approves a prompt in the headset instead of typing a password.
Port 32000 closed, a timeout or a 403 falls back to the existing
password copy. The Host frame block lists both keys; a host counts as
found if port 22 or 32000 answers; with no host given, dns-sd or
avahi-browse look for _steamos-devkit._tcp. Inferred from Valve's
source, not yet verified on a Frame.
