Auto-defined SoundBanks in Unity

With the introduction of auto-defined SoundBanks, which rely on the Project Database to work, the default Wwise Project Settings after integrating with Unity have changed. 现在其包含以下必选设置：

• Generate JSON Metadata
• Object GUID
• Object Path

由于这些更改，现已停止使用 XML 文件。不过，只是保留之前生成的 XML 文件并不会损害到工程。
