[Cryptech Tech] Tamper detection

[Jakob Schlyter]

Richard Lamb has offered to help out with tamper detection and the plan 
we have come up with is that he will create a small tamper daughterboard 
that connects to the 10-pin tamper GPIO on the alpha board, along with 
some updated code for the AVR. Once we have more experience with the 
tamper circuits, we can fold the components into the main board.

For this to be really usable, we need a battery on the alpha board. This 
can be implemented by adding a battery holder to the next rev
and/or adding an external battery to rev03. Rick suggested that we might 
want to use a larger battery in combination with a supercapacitor so the 
battery can be replaced without loosing the MKM.
