Pre-check the public keys array, season heights, and timestamps
before launching the daemon. This check prevents the daemon from
launching if some information in the important arrays is incorrectly
filled.

In the real KMD chain (not in the first blocks),
block.nBits will always be greater than KOMODO_MINDIFF_NBITS.
Therefore, the control will never enter this conditional statement.

Also "fee stealing" is impossible, since we have notary
proof tx (last tx in notary mined block).

For some reason, we were not allowed to have additional
vouts in the coinbase transaction if their total was
greater than 0.1 KMD. Therefore, a coinbase transaction
with 2.8 KMD in vout[0] and 0.2 KMD in vout[1] was forbidden.

Since this release, we are allowing such transactions.
We are not using height activation here to keep the code simple;
instead, we have just removed the restriction itself.
