Changes: - Merged app::cmd::ObjectIO into doc::SubObjectsIO - Changed app::cmd::SetCelImage with app::cmd::SetCelData - Added Cel::createCopy/Link() to avoid confunsion with Cel copy ctor - Renamed Sprite::getImage() -> getImageRef() - Added Sprite::getDataCelRef() - Added doc::CelsRange helper to iterate cels - Added Sprite::cels()/uniqueCels() member functions (removed Sprite::getCels()) - Added DocumentRange::convertToCels()
