Janet now uses the compromise library to process commands, meaning she has NLP! Commands now only have to contain the right phrases, e.g. "play a video" and "play the video" both trigger the same command, regardless of the rest of the text

Simplified the events dispatcher because shared memory references were causing events to be dispatched multiple times
