The "Depends on" field is used to indicate when one change depends on another. It would be very useful if it could react when those dependencies are marked as submitted by setting a strikethrough on the text. That way, users don't have to click through to see whether or not the dependent change has been committed yet.

Manual testing: marked a dependency submitted, observed it show up with a linethrough in the "Depends On" list for another review.

All tests in djblets and reviewboard pass.
