[ANNOUNCE] Casascius-compatible address tool for Android.

Some suggestions/improvements for security:

- On the newer androids, the screenshot of the last state of the application is saved when switching programs.
 Unfortunately, there might be no way to fix this when a user switches apps.  Providing an exit button would be an option for those that utilize it.

- When scanning the public key, a rogue QR app scanning app (or a third party person) can see the brainwallet passphrase.
Suggestion to display the QR code with a full screen white background.  Additionally, bitaddress.org has a hide/show password for the brainwallet, can add a checkbox to show typed passphrases as ********.

-Lock the screen orientation upon startup, or do not allow a change in screen orientation to exit the QR code on fullscreen.  Again, a rogue QR scanning app, trojan with webcam access, or third party human will see the brainwallet passphrase and privatekey.

Can you consider making one app (or two separate apps) that replicate the features of bitaddress.org and brainwallet.org.

I'm not familiar with android development, but all you need to is package the github html and javascript files and the app is just a no permissions no internet access browser.  You start the app, choose brainwallet or bitaddress.  And voila, an offline version!
