Upgrade to boost 1.72, current secp256k1, zeromq and consensus sources, as well as removal of qrencode, png and zlib dependencies has been merged. NuGet packages for secp256k1 have been uploaded, though I'm not intending to update NuGet for zeromq. Instead I'm planning to move to vcpkg, which is c++ oriented and includes more current boost packages, and includes well-maintained zeromq packages. secp256k1 packaging continues to be a problem as the library is not versioned, so I'll end up building (only) and maintaining a package for it. Once this is complete I will create vs2019 project files and remove generation and testing of vs2013 (vc120/c++11 CTP). There are Travis breaks on all macOS builds due to a Travis change affecting boost installation. I'm going to resolve this next, and add builds for the Travis big-endian and Windows platforms. Also on the build roadmap is generation for mingw builds and VS code projects for all three platforms.
