sortable:
- merged back all position and scroll fixed from draggables - renamed accurate to accurateIntersection and set it to true by default - refactored intersection code (no change in logic) - added forceHelperSize option (default: false), a forced helper size is also triggered when the generated helper doesn't have any styles set for width/height, so this option won't be needed in most cases
