Fix bug when pasting multiple times in a row

In Cells, images, and tokens are automatically selected & floated when pasted I mentioned that I found a bug today: if you pasted data multiple times, any tokens and images would get messed up such that when you deleted one you’d delete them all (same with moving any of them).

I thought I was going to wait until tomorrow to fix it but I had a nice and simple idea on how to fix it so I did it just now.

Happy Shmepping ya’ll!
