Show icon on feature cards when it has been promoted from an idea

When shipping a release I go back through the features and try to find the ones created from ideas so I can update the Admin comments for those that have now shipped.

At present I have to open each feature card to check if it was raised from an idea. It would be far easier to have the option to show an idea icon on the feature card.

It would also help developers to see which ones have related ideas to view them and their comments
