Missing parenthesis when displaying coordinates

[Brett208]

When showing the user coordinates to where robots complete or cancel tasks, the leftmost parenthesis and space is missing.

MapViewState.cpp

mNotificationArea.push({
	"Robot Task Canceled",
	robot->name() + " canceled its task at" + std::to_string(tile->xy().x) + ", " + std::to_string(tile->xy().y) + ").",
	tile->xyz(),
	NotificationArea::NotificationType::Information

This could be fixed by just adding the parenthesis and spaces in these places.

I think a better fix would be to create a ToString overload on Point and Vector in NAS2D that autoformatted the (x,y). This is slightly complicated by the classes being templates. Then a lot of the manual coded formatting in OPHD could be removed in favor of calling tostring the basic types. NAS2D's Rectangle would probably also benefit from this.

An intermediate solution could be to try to consolidate all the calls to a single helper method in OPHD if NAS2D isn't available to edit.
