Add building Chocolatey packages for the net461 FDD #39
Description
Don't replace the existing ones, but add them additionally.
That way users can choose between using the Chocolatey package that requires Microsoft Visual C++ 2015 Redistributable Update 3 to be installed, vs the one that requires the full .NET Framework to be installed.
Maybe even add one for the net451 FDD, for Windows 8.1 and Windows Server 2012 R2 users.
As there's a build-chocolatey.sh Bash script that gets used in build-with-docker.sh, the net461 FDD needs to be builable in a Docker container as well. This is part of #38.
