Audio manager
Created by: thomasduhamel
Introduces a full audio manager as a nice middleground between the ExperimentManager and the VAUnity framework.
You can now specify:
- a list of audio files and their duration per block in the JSON configuration;
- if you want them in a random order (based on the seed already here);
- a duration of silence between the audio files;
- the folder where the application fetch them via the settings interface.
