VS 2015 + .NET Core

This release adds support for the new .NET Core and .NET Standard framework monikers so that packages like System.Runtime can be handled correctly.

The release also drops support for net40 on NuGet.Lucene, which now only supports net45 or later.

The following bugs were also fixed:

• Fix incorrect path encoding of OData characters like ()
• Fix invalid DateTimeOffset when running in GMT+ time zone
• Set Cache-Control header on API responses to prevent browser caching of API responses
• Preserve IsMirrored flag when synchronizing previously mirrored package
• Set Published date to date package is uploaded to avoid spurious syncing
