More work on the Crypt Keeper.

* Use the DPM to determine if we are encrypted.
* Fix misspelling (Comfirm -> Confirm).
* Animate to black when enabling encryption.
* Add holo droid background.
* Change the progress bar to indterminate.
* Display the percentage complete in the status line.
* Fixed bug 3388097. You will no longer have to unplug your device to start encryption. This line is intentionally long. I could make it shorter but I am proving a point: <magic>overflow: auto;</magic>.
* Actually hold onto the wakelock to prvent the device from sleeping.
* Implement onStop() as a orientation change can happen at boot. This will start the activity twice and there will be multiple handlers with messages.
