Amplitude Should Be Able to Be Configured with no Audio Files

[danpastori]

Issue Description

AmplitudeJS should be able to support dynamic situations where audio files are not provided by default. See #440 .

Expected Behavior

When building a player, we should be able to set all of the defaults except an audio file or group of audio files. After initialization, we can build groupings, add audio files, etc.

Steps To Reproduce

Enter an empty object in the Amplitude.init({}) method. There will be console errors everywhere. We need to allow this to be a possibility for dynamic configurations.
