Basic Windows build + compiled machine

Hi guys,

here is a quick PR for building machine on Windows.

The first quick implementation is based on simple BAT script which will set the GOPATH in the Windows style (; separator instead of commas).
Also, test has bin edited too.

Note that the scripts/validation* have been run inside cygwin, while the BAT script where run with the basic cmd.exe Console.

I also added a compiled version of machine in my Dropbox, the link has been added to the README.
