Feature: Voice triggering
Feature: Voice triggering

Pocket Sphinx voice triggering implementation wrested from the
AlexaPi project, stripped down to mostly the bare essentials,
though probably can be further optimized.

Performance is OK with a standard ceramic mic.  I'm using the
keyword "Pal", which actually works pretty well (and doesn't
get my Echo in the same room excited).
