Project "due date" option (just like a task due date).

In each one of our projects we have tasks, sometimes multiple tasks. Those have due dates (and TeamBox currently supports)

But the overall project also has a due date for all the projects we manage. It would be very helpful if TeamBox was to add that feature to projects. A simple due date box, when creating the project. With the ability to edited at a later time if needed. Let's do it!
