Switched to Wit AI

Switched to Wit AI ("open" is now broken.)
Jarvis now does NLP (Natural Language Processing) through Wit AI.
Basically, he's awesome.
He can:
-Say hi
-Play any mp3
-Pause/unpause
-Say whatever you tell him
-Exit through a command
Some things he'll hopefully be able to to in the near future are skip
to a given time in the mp3, fast forward, rewind, open
files/applications, and accept commands through voice input.
