This is a simple editor for the new dictionary object.
You start with a key and a value to input. Then you have a button to add a key, and then an export button for when you are done.
Note: Value is saved as a number, so if you put a string you'll just get zero.
I've also added a scroll using mouse wheel for when you get more keys than can fit on the screen.
If people want to do more with this I'll add stuff like web storage etc, but could we get a download prompt pop up, or similar added?
Even a way to get the url would be fine.
