(Partly fixed) Don't create empty "Track Pictures" and "Audio" folders when not used in project

A small suggestion to keep the project folder free from clutter: if you don’t ever Track Pictures then this empty folder doesn’t need to be in every project folder. If there is no audio in the project, then the empty Audio folder isn’t needed.

EDIT: “Track pictures” folder does no longer seem to be created.

Completely agree. It just makes a mess. I never use track pictures anyway!
