Build the sample nugt packages together with the TypeProvider package

[forki]

And macke the type provider package a dependency.

@dmohl How can we automatically check if the samples are still valid.

That's a good question. I believe that we could create some sort of automated end-to-end integration test, but it will likely take some time to figure out. A quicker option might be to setup unit tests with code that matches the samples. That will atleast allow verification of the sample code.

I'm closing this for now, it feels like samples are better presented via web documentation, see #237?
