Eliminate msi package

[CharliePoole]

Following a brief discussion under issue #1432, we will eliminate the msi package for the next release. Because the next major release, 2 .0 is already in beta, we will do this breaking change using a minor version upgrade: 3.18.

Since this is the only msi package we create, the functionality of creating msi packages may be removed from the scripts at the same time.
