*sound doesn't work on web version

Embarrassingly, I think this has always been broken, or at least for a very long time.
The short of it is that we pass the game files as a compiled object, so there's no need to load individual scene files.

This of course doesn't apply to media included within the game, which are still being referenced as "file://{projectPath}/resource" -- which doesn't exist on the web. We actually need to grab the media via Dropbox's API.
