Subject: [PATCH] OI Safe: large patch, added Search activty, completely redid
 autolock, added preference 'Lock on screen lock' with default of true.
 autlock is no longer dependent upon CategoryList, which if not active would
 cause app to go unlocked.  Instead each and every activity listens for the
 broadcast from the service to know to autolock.  None of the activities
 finish() upon lock but instead launch FrontDoor to present user with
 AskPassword.  Upon unlock the user is dropped right back where they left off.

Started using Android 1.5 features like onUserInteraction() which allows
the user to do anything with the app and cause a reset of the timer.
OI Safe now requires 1.5 as a result.
