using Symata fails for Julia 1.0.0 on Windows

[metanoid]

I know I'm being too eager expecting this to be working 2 days after Julia 1.0.0 is created. Just thought I'd create the issue in the meantime.

1.0.0 and Windows at the same time! This is brutal. Thanks for the issue, please open anything else you see fit.

Symata passed CI on 0.7 while I was packing for JuliaCon; broken by the time I gave my talk.

[jlapeyre]

Most of Symata works now on Linux under Julia 1.0. This is Symata v4.4.5. It is tagged but not in registered in METADATA.

There are some changes in... PyCall probably that cause some tests to fail. These remain to be fixed.

I have not tried on Windows yet.

The most recently registered version v0.4.5 works for me with Julia 1.0. This is on linux. Please open another issue or comment if loading still fails.
