Andrew Ozz 6a2ef2d5b2 Fix and improve arranging of postboxes/metaboxes: ... - Enable arranging only when the Screen Options tab is open. - Prevent accidental/unintended dragging. Seen it happen mostly on laptops when using the mousepad/trackpad. - Improve discoverability and usefulness by always showing the "drop zones" outline when postboxes are draggable/arrangeable. - Add some (brief) explanation to the Screen Options tab helping the user understand what options are available and how to change them. This is especially helpful for screen reader users to give an idea how to use the screen options and what to expect. - Fix/enhance some of the code in `postbox.js` and make it coding standards compliant.
