List unused resource files in a GameMaker:Studio project.

list_unused,py

# Lists files in a GameMaker: Studio project that are no longer referenced by the project.
# Helpful for when you forgot to enable "Delete from resource tree deletes from disk" in Preferences.
# NOTE: THIS IS VERY INCOMPLETE AND BARELY TESTED.
# Made for Python 3.x
