Audio resource kind

Audio files must be supported. Metadata labels labels (`duration` and `bitrate`) should be displayed on their icons similar to how they are displayed on icons of video resources (`duration` and `resolution`).


Start by tracing the existing video resource icon handling, where duration and resolution are displayed. Use that path to identify how audio resources are represented and where duration and bitrate metadata should appear. Done means audio files are supported and their icons show duration and bitrate in the same manner as video icons.
