Visibility toggle styling is awful on wp-admin

[boonebgorges]

When editing a user's extended profile via wp-admin, the styling for the visibility settings is pretty terrible. See the attached screenshots.

I assume it's just inheriting the styles from the front-end. Some padding and font-size fixes would go a long way. Something should probably also be done about the fact that wp_editor fields are full-width, but the visibility settings are indented - I'm open to suggestions about that.
