Committed a small revision to the current source code, https://github.com/Sterlingcoin/Sterlingcoin-1.6.2.0-Release

Maintenance only, a more-recent checkpoint and updating copyright years. No plans to build and release Windows and Mac binaries at this time, there'd be little benefit and attention should remain on development of the new code.

This is to update the current code for the new year and to not have the repo appear stale. Well, too stale. Apologies for that. What little development time that could be afforded this past year was focused on development of the new code. Unfortunately, and as you know, that was not completely-fruitful. Fortunately; it can and is being brought into greater focus now.

Just getting ready to roll into the new year 2020 ready! Have a safe and happy New Years, Sterlingcoiners!
