LitecoinDark v1.2.2

Release Notes:
=============

Version 1.2.2 of LitecoinDark contains a few relatively simple changes to help
us to lower the block reward and extend the mining period for LitecoinDark.
First and foremost, as of the time of release, block 60000 is roughly 96 hours
away (slightly more than 96 hours, but this should be adequate time for
exchanges and pools to update).  In order to ease the transition, a simplistic
difficulty engine moduel has been implemented using difficulty shield which will
reset the block's difficulty to the minimum starting difficulty for exactly one
block.

After this, difficulty shield will switch back to the KGW module and regular
difficulty adjustments will occur.  This will ensure that the blockchain
including the new hard fork code is long enough to survive even if a large pool
elects to skip this update or does not see the announcement in time.

This will inevitable produce a number of extremely low difficulty blocks and
orphan blocks to emerge, however, the network will quickly compensate.  However,
as the goal of this fork is to extend the mining period, having several blocks
found almost immediately works against our goal.  To offset this, we have
decided to reduce the block reward to 16 instead of 24 and continuing regular
halving intervals.
