Fix License information and packing the sample files.

[CaptnCodr]

While packing the nuget packages using dotnet paket pack ... the following warnings appeared:

After that I downloaded the sample packages, depacked them and found no content in it.

Click on "License Info" refers to "https://github.com/fsprojects/FsUnit/blob/master/LICENSE.txt" but it's "license.txt":

Is it show the same warn if you use NuGet target from FAKE script?

[CaptnCodr]

Yes, it is:

The content of the sample packages are only the "*.nuspec", a "[Content_Types].xml" and "package\services\metadata\core-properties\coreProp.psmdcp"

With this fix we have another folder "content\netstandard2.0" with FsUnitSample.fs.pp in it.

Got it, thanks. Feel free to merge it when it is done

[CaptnCodr]

For sure.

And releasing it as 4.0.2 to have the packages deployed properly?

Will merge it tonight.
