Normalize line endings
Fixing Windows 7 templates so they work again after the transition to
vagrant-windows.  Windows 7 does not respect the network adapter location
in Sysprep and WinRM requires a non-default location setting to work.
Modified the templates to set the network location manually and refactored
the WinRM install out of Autounattend.xml for easier debugging.
Adding support for PROVISIONER & PROVISIONER_VERSION to Makefile
Adding script to optionally uninstall cygwin on Windows 7 after provisioning
with packer.  Also parametized the shutdown_command parameter in all the
Windows 7 template files (to make this optional).
