Milestone scheduled end

[ari]

Tasks have a forecast date, we want milestones to also have a forecast date which is (in groovy pseudo code) milestone.tasks*.end_date.last(). Although this is denormalising the db, it might be useful to store. We could go slightly further and add the time estimate to the task_start date, extrapolated over the scheduled work hours for the assigned user.

We need to display this date in the UI in both the milestone list view and in the task edit view (next to the milestone dropdown).

We are going to add field to milestone table and store forecasted end date there updating on any task changed?
