Add support for sprite object (#1488)

## Launch Checklist

- Fixes #1302

When a sprite object is used, the current settings modal does not
present it well and does not allow editing.
This changes the input from a string to json.
It does make the editing a bit more cumbersome as you need to type `"`
now instead of just placing the address, but if you click the info
button you should be able to understand that this is a special field.
The fact that it looks like a code editor should also help guide users
to place different input there.
