Middle import script stopped working because of the Godot change from paths to uuids. #40
Description
When I add new asprite files to my Godot project, I can no longer get them to run my middle import script. But the asprite files that I already had in place continue to work.
I can see, if I open up the ".aseprite.import" files in notepad, that the old ones have the path stored to my middle import script, while the new ones just have a UUID. It looks to me like importality is trying to use the UUID as if it were a path and failing.
