	Accumulates how long a project has been the active tab, purely locally:
	the value lives only in the project's own file (a <usage> element next
	to <properties>) and is never transmitted anywhere.

	The owning code (QETDiagramEditor) is expected to call setActive(true)
	when this project's tab becomes the current one, and setActive(false)
	when it stops being current (tab switch, project closed, ...).
