TITLE: BackDoorLock hack - prevents silent updates

NOTES:

This simple extension has only one purpose: stop Amazon from updating your Kindle silently without your explicit consent. It is intended for users who believe in "My device - my rules" principle.

It doesn't stop Kindle from downloading the update file but once it is downloaded, any silent installation attempt fails instantly in an early stage without depleting the battery and intercepting the GUI.
The update file is preserved after such failed attempt and thus it is not downloaded again and again.
Full updates are recognized during the attempt and a countermeasure is deployed (dummy update file update__this-file-prevents-installing-on-reboot.bin is created to confuse the boot-time updater)

Manual update triggered by user is still possible (i.e. selecting "Update Your Kindle" in the menu).

You can install the extension as a classic update bundle or a KUAL extension. Please do not install both.
See UPSTREAM for details.

EXTRA NOTES:

The eips reports are all fixed up now on all devices. (Version 6.0 or later)

The Touch and PW are supported (Version 7.0 or later)
