Innocuous warnings on package build

[kaosborn]

Compilation of the .NET Standard library outputs the following warnings:

warning : Issue found with package 'Kaos.Collections'.
warning : Issue: Consider providing Summary text.
warning : Description: The Description text is long but the Summary text is empty. This means the Description text will be truncated in the 'Manage NuGet Packages' dialog.
warning : Solution: Provide a brief summary of the package in the Summary field.

These warnings may be safely ignored. The cause of these warnings are the long length of NuGet description. This description is used by the NuGet.org site and cannot be specified any other way.

Hopefully the Visual Studio team will fix this someday.
