Converting FX with AudioSource to use CWPlayAudioScript instead

[Saito197]

Resolving #5 by converting AudioSource to CWPlayAudioScript.

There is no "SaveAsPrefabAsset" in Unity 2017 so after converting the GameObject I had to Drag 'n Drop it back to overwrite the old Prefab (which I used an AHK script to automate).

Changed files include all prefabs with AudioSource component in the root GameObject in:

• Assets/PrefabInstance
• Assets/Resources/particle
• Assets/Resouces/props
