[Feature Request] Replaceable sound effects in the audio editor.

This would basically be similar to how you can replace the music tracks in the audio editor with streamed music files. I know jamer's audio tool exist but this would be a nice addition.

Start by comparing the audio editor's existing streamed music replacement behavior with the requested replacement of sound effects, and review the referenced jamer audio tool. Define which sound effects are replaceable, how streamed files are selected and loaded, and what behavior demonstrates that the feature is complete.
