Transactions are now propagated to peers from which we have not yet
received the transaction. This will significantly reduce the chatter on
the network.

Moved new mined block handler to the protocol handler and moved
transaction handling to protocol handler.

Set the state for the managed tx state instead of creating a new
managed state.

Implemented a new transaction queue. Transactions with a holes in their
nonce sequence are also not propagated over the network.

N: 0,1,2,5,6,7 = propagate 0..2 -- 5..N is kept in the tx pool
