Fake build

Here is the fake build !

It builds the project, run tests, package and publish nugets.

To get the help:
    build.cmd help

To build all:
   build.cmd all

To build and publish nugets:
    build.cmd nugetkey=<the key>

The version is read from the RELEASE_NOTES.md files. The release notes are also used inside nuget packages.

the rake build works side by side.
