Sandbox: Support setting/modifying metadata

[calebjacob]

As of now, the sandbox publishes components without setting any metadata. It would be cool if we could expose a way in the UI to set/modify at least parts of the metadata schema for each component.

@thisisjoshford can you think of any reason we would want this for the alpha test or are we safe to push it until after?

[calebjacob]

Good point, this probably can wait until after alpha test.

This isn't critical for alpha. Safe to push until after.
