This required using the new Steps::GetTimingData function and the allowEmpty parameter to TimingData::TidyUpData when appropriate, as well as clearing the TimingData to remove step timing rather than coping the song timing over it. Fixes some odd editor behavior when changing song timing, and is overall a slightly less hacky way of doing things.
