Default miner should distribute work over the network for a block candidate.

[jquiroga]

Since default miner is now useless. Why not try distributing work for a given block candidate over the network just like the big boys do it in their private networks?

Options:
1. Send the given block candidate to all peers with a starting value for the nonce and a final value for the nonce.
2. Just randomize starting value for the nonce. (It could be seeded with the local ip address).
3. Give another.
