Implementing boost/ignition cut

[b_boy]

The very soon to be release Element Tuning Hydra system of the WRX and STi will also have the ability to receive signal and cut boost/fuel in the event of a WI malfunction. I'll be writing up a method to do it as soon as I can implement it.

I'd like to see much more discussion of this topic. I think it's a major hurdle to more wide spread WI use.
