WAV Trigger Update

I've been torture testing firmware v1.00 for over two weeks now. Using an Arduino UNO and the serial control port to alternately max out with 14 voices for a period of time, then letting the WAV Trigger enter low-power sleep mode, waking it up and repeating. I'd strongly advise that everyone update to this version - there's no reason not to and many reasons to do so.

I also just updated the InitMaker app to include support for the new low-power sleep option. After taking some actual measurements, it appears that putting the WAV Trigger into sleep mode results in a reduction of supply current from around 80mA (quiet) to around 5mA. I'm assuming that the majority of this sleep current is coming from the microSD card, which remains powered. In addition to not having hardware support for removing power, the SD initialization time would likely increase the time it takes to come out of sleep mode. So I deem this to be a reasonable trade-off.
