All AppVeyor builds are failing

[Jon Dufresne]

For example,

https://ci.appveyor.com/project/ionelmc/python-tblib/build/master-50

This make contributing more difficult as each PR shows a build failure. It is hard to know if a change is introducing a regression or simply failing as before.

@jdufresne i'm looking at the failures now.

PS. I plan to do a 1.4.0 release today after sorting out the CI.

Released v1.4.0.
