Pin mkl to fix Appveyor Python 3.4 builds (#315)
Pin mkl to fix Appveyor Python 3.4 builds (#315)

* Pin mkl=2017.0.3 to fix Appveyor Python 3 build

Without pinning mkl, Python 3 was using mkl=2017.0.4 on Appveyor,
which was erroring with "DLL load failed" as described here:
https://github.com/numpy/numpy/issues/9933

For the time being we can get our Appveyor build working again
by pinning mkl=2017.0.3, and hopefully upstream will fix soon.

* Fix appveyor graphviz link rot

* Fix Kappa download links

They renamed an existing github tag, which broke the link :-(
