PCoin v1.2.1 — fixed seeds, so a node can always find the network

Bootstrap fix. A node could only find the network through one DNS name. If seed.pc.am was down, DNS was filtered, or the node was started with -dnsseed=0, it had no way in at all.

What changed

src/chainparamsseeds.h still held Bitcoin's mainnet seed list. Nothing included it, so it was dead code — and that was the only thing stopping a PCoin node from dialling Bitcoin nodes. contrib/seeds/nodes_main.txt, the generator's input, held the same 2031 Bitcoin addresses on port 8333, so anyone following the documented regenerate step would have written them straight back in.

Both now carry PCoin's three seeds, and mainnet compiles them in as vFixedSeeds:

35.239.156.16:9444
35.238.47.14:9444
178.105.3.51:9444

Verified with a fresh datadir and -dnsseed=0: "Added 3 fixed seeds from reachable networks", all three connected within ten seconds, on both Linux and Windows builds.

nMinimumChainWork stays zero and the assert enforcing that is untouched. PermittedDifficultyTransition() still returns true unconditionally above lwmaHeight, so a non-zero minimum chain work remains unsafe; the work to give it a real LWMA bound is not part of this release.

Still the deadline that matters

LWMA activates at height 2800. Every node must be on v1.2.0 or later before then — a node still on v1.0.x at that height will follow a different chain. This release includes everything in v1.2.0.
