v0.2.1

BitHanko 0.2.1 and Signer Lockdown 0.6.1.

Warning: This is experimental software. It has not been audited and comes with no warranty. Keep amounts small.

Security: Signer Lockdown 0.6.0 and earlier did not keep airplane mode on (#64)

Applying the restrictions made Android turn airplane mode off and keep it off, so a locked phone with a SIM card went back online. Lockdown set DISALLOW_AIRPLANE_MODE, which Android treats as "airplane mode is not allowed", not as "keep it as it is".

If you use Lockdown:

1. Update Lockdown to 0.6.1 (Update an app from an SD card, or from a PC over USB). Opening it clears the old restriction
2. Take out the SIM card and turn on airplane mode
3. Tap Apply restrictions again

Lockdown 0.6.1 no longer claims to hold airplane mode on, since Android lets no app do that. Instead it leaves the radios nothing to join: it applies only with no SIM card, keeps the Wi-Fi and Bluetooth settings locked, forgets saved Wi-Fi networks, and disables quick settings while locked. Airplane mode can still be turned off in Settings.

BitHanko itself is unchanged apart from the version.
