Common Art 3 - Sprint #2 Delivery

 For this sprint, I spent a good portion balancing audio so that the Emmi sound effects, the music, and the ambient sounds wouldn't be too loud compared to each other. I also helped out with connecting the new scan effect to the steps so that only the current active step would highlight while the others would not. The Emmi blueprint was also adjusted to have 2 more movement states, a scanning state and a strictly idle state, that get called at different times.
