Harmony

This is the v0.13.1.0 GUI point release #2 of the Italo software, and it is part of the v0.13 network wide update. That major release was due to the December 5th network update, which in turn enabled Bulletproofs PAD for reduced transaction sizes, sets the ringsize globally to 11 for uniformity of transactions,, and finally sets the max transaction size at half of the penalty free block size. This release of the software presents a number of major improvements to Italo, as well as a large set of bug fixes. It fixes the coinbase bug!
