Indicator on projects with manual update

[#1]

If a project's update setting is set to not automatically recalculate timelines, users do not realize they have to manually recalculate timeline to propagate changes. It would be helpful if the project had a clear indication (like a button that says "Recalculate Timeline") that is displayed on the project header area or task menu bar like AutoSave that indicates that user must press this to recalculate timeline. This would not be shown if automatic recalculation is set for the project.
