Tag field - allow re-ordering using pivot

[matthewjumpsoffbuildings]

It would be great if you could re-order tags in the Tag field. It should ideally allow drag and drop re-ordering.

The way I have done it with a custom field I was using was to use an order column on the pivot, that seems like a common sense default, but it would be good to have a method like withOrder('pivotOrderColumnName') so you could specify it
