MimeKitLite (on NuGet) misses WP8 support

[hohl]

Thank you very much for this library. You've done a really good job by devloping framework. But I only need a very little subset of functionallity (stuff in Encoding and the Rfc2047 util, to encode MIME Headers) for my Windows Phone app.

While the NuGet package MimeKit supports Windows Universal packages, the MimeKitLite package doesn't. It would be great if you could fix that in the next release.

The next release will include the Windows Phone assemblies
