full windows support

[vitiral]

Windows support is still not where I want it to be.

What I want:

• compile with linking to the windows libs statically. Used to work but suddently broke in Appveyor.
• package in a msi or exe package that:
  • installs into somewhere on the PATH or whatever equivalent to windows
  • adds a run artifact here option when right-clicking in a folder. This will basically just run art server in any location.

I suppose an MVP could be some kind of windows GUI for running the server.
