Fixed a long-standing, subtle nuisance in Map. There's a cutesy check to hide the US Country layer when the state or county layers are visible. This exposes the Great Lakes, whose absence in the country layer has always annoyed me. However, when enabling both and then disabling one, the country layer would be reinstated, even though it wasn't needed because another layer covered it--manifesting as showing the Great Lakes as otherwise land. Subtle, but annoying. This fixes that.
