Names set do not follow when swapping / reordering the desktops

[chipbite]

When you swap virtual desktops (reorder them), the names set do not "follow".

So I have foo1 -> foo4. If I swap foo3 and foo4, foo3 windows will be in the fourth place, but it will still be named foo4, and the same for the other desktop in the swap.

Would be nice for the naming to follow when swapping.

I suspect that #16 would address this too.
