protected boolean allowTerminatingTasksWhenClosing() {
		return false;
	}
Normally, tools are not allowed to close while tasks are running in that tool as it
could leave the application in an unstable state. Tools that exit the application
(such as the FrontEndTool) can override this so that the user can terminate running tasks
and not have that prevent exiting the application.
@return whether the user is allowed to terminate tasks so that the tool can be closed.
