restore secrets automatically on reinstall

[GoogleCodeExporter]

This is a feature request to implement the backup/restore functionality 
described at http://developer.android.com/guide/topics/data/backup.html.

This will allow the encrypted secrets to be automatically backed up to Google's 
servers whenever they are updated (maybe as a user-selectable option since some 
users might not want their secrets sent to Google, even if encrypted), and then 
automatically restored when the user reinstalls their device from scratch or 
switches to a new Android device. This also helps if a user loses their phone 
and gets a replacement since they won't have to worry about losing their 
secrets.

Sorry for not checking if the feature was already there! It didn't restore for 
me the last time I reinstalled my phone so I assumed Secrets just didn't 
support it. If the restore fails to happen next time I try reinstalling, I'll 
file a bug report for it. Thanks.

Hi happily.oblivious,

While I closed this bug as a duplicate, your comment prompted me to double 
check the code.  It turns out that Android has changed the way that apps 
integrated with the backup service since I first wrote the code, and now 
requires that each app register for a special backup key for backup/restore to 
work with the standard Android Backup Service.

So I decided to open a new bug to track this, see issue 87.  Thanks for the bug 
report!
