[openstreetmap/openstreetmap-website] Ensure IE/Edge compatibility for routing drag&drop (#1344)

Use the DataTransfer interface properly, using the `text` format, as IE/Edge does not support much more. We can JSON-serialize anything there, even though right now, only a single string would be enough. (This might be unnecessarily complicated right now, and in the spirit of KISS, we might use just `dt.setData('text', $(this).data('type')` and `type = oe.dataTransfer.getData('text')`. Your call.)

Also, IE does not support .setDragImage, so check for support prior to calling.

Fixes #1343
