Add a "future release" icon to contribution mode

Ken posed a good question on the intradoc forums. He wrote:

Our editors have requested that we add a "Future Release" indicator to the Site Studio contribution mode screen, similar to the workflow icon that can appear... Does anyone know what the syntax for accessing the metadata of the content is?

I thought it was a great idea, so I looked into it.

Hiding primaryFile for SiteStudio

Kyle has a great article on hiding the primaryFile field from Content Server checkin pages. I just wanted to augment the solution by mentioning a way to hide the field only from SiteStudio checkin pages.
