Can overclaim land in the middle of a claim

If a faction is overclaimable, you can overclaim ANY chunk, not just chunks at the edge of their claim. This means that if a faction has 1 fewer power than land, you can go straight for their most critical chunk. I'm pretty sure that on the old servers, you had to start overclaiming at the edge of the claim (presumably, the chunk had to have at least 1 adjacent unclaimed chunk on the 4 sides), and it would say something in chat along the lines of "You must start claiming land at the border of the territory." This should also potentially take the world border into account (i.e. a border edge claim, or border corner claim can't be overclaimed if the only adjacent unclaimed chunks are outside the border)
