Adam Wathan e8b64fdb62 Move negative margin logic into a helper
Adds a new `utils` bucket that's passed as a second arg when using a closure for theme values. The idea is you can destructure useful helper functions out of this argument, in this case a `negative` function that converts a positive scale to negative values. That's the only helper function right now, but making it a destructurable arg so we can add more if necessary without adding a bunch of positional arguments.
