heritage: Stealthcoin

problems:

* MAJOR: Block reward scheme gives founders a practical premine when combined with a ninja launch.
** At least 1 block was officially premined, 2 minutes before launch. 
** First 35 blocks were mined within 1 minute from launch to the same address (first 30 blocks contained the biggest rewards)
** Difficulty adjustment of 30 blocks also makes this seem to be intended
* MINOR: Genesis seed is not a news event


notes:

-//     hash(nStakeModifier + txPrev.block.nTime + txPrev.offset + txPrev.nTime + txPrev.vout.n + nTime) < bnTarget * nCoinDayWeight
+//     hash(nStakeModifier + txPrev.block.nTime + txPrev.offset + txPrev.nTime + txPrev.vout.n + nTime) < bnTarget * nCoinDayWeight * 10
+// (the 10 was added for the short staking times of Stealth (36 hr --> 216 hr full wt))


+    if ((nTime >= CUTOFF_POW_TIME) && (IsProofOfWork()))
+         return DoS(100, error("CheckBlock() : Proof of work (%f BLKT) at t=%d on or after %d.\n",
