Create "symbol packages" so NuGet clients can hopefully step through …

…source code.

Nuspecs: target="readme.txt" doesn't work, it creates a folder.

 The Loyc Core project is a set of general-purpose .NET libraries. LoycCore is especially focused on collections - classes, interfaces, adapters, and extension methods - but also has code in other areas, most notably parsing and syntax trees.
 
-**IMPORTANT**: Development occurs primarily in the [Enhanced C# repository](https://github.com/loycnet/ecsharp), which contains this repo as a "git subtree". However, `git subtree push` mysteriously stopped working which means that synchronization with this repo has become a manual process. As a result I would ask you **not to use this repo anymore**. We'll just do everything in ecsharp.
-
 Contributors are welcome: more unit tests, code reviews, and new features are desired, anything relatively small (under about 3000 lines of code) that fits the theme "things that should have been built into the .NET framework, but aren't".
 
 Please visit http://core.loyc.net for documentation.
