Can now specify custom decoder when instantiating Microphone

[edouardpoitras]

This is also useful if you want to use the Microphone's listen() method without setting up a pocketpshinx decoder, by specifying a dummy decoder:

class DummyDecoder(object):
    def start_utt(): pass

mic = Microphone(decoder=DummyDecoder())
data = mic.listen(duration=5, timeout=1)
# Do stuff with data, like UDP stream to server.
