Destroy data with special password and/or decoy keyfile.

[Rakly3]

The title says it all.
Ability to set a password that, when entered, destroys the data. Preferably without pop up message saying you did.
Or by using a 'decoy' keyfile.

While at it, might add a configurable list that destroys all volumes in that list. So you don't have to go through each one by one.

Tie decryption to unique hardware ID's, ie the hard drive. Making clones inoperable. Ie against parallel brute forcing.
