[WIP] And then there was QED

As part of transitioning to using QED for our build server...

That's right:

This resolves #119. Prepare yourselves.

But first, there's some housekeeping we need to work through:

- [ ] build script changes

Currently we have a monolithic `build.fsx` that does everything we need. I had to break this up a bit because of how we wanted the build scripts to run on the build server.

So developers will still have the `.\build.cmd` script for their local testing. I've dropped creating NuGet packages as part of this build, because you probably don't care about that.

For QED we'll point it at `.\script\cibuild.ps1` which will run each these step incrementally:

 - build
 - unit tests
 - integration tests
 - create packaages

And get a clean output if All Is Well.
