winrm sections in Vagrantfile?

[docwhat]

When I try to use your repository, it doesn't work unless I use a custom Vagrantfile.erb that contains:

  c.vm.guest = :windows
  c.vm.communicator = "winrm"
<% if config[:username] %>
  c.winrm.username = "<%= config[:username] %>"
<% end %>
<% if config[:password] %>
  c.winrm.password = "<%= config[:password] %>"
<% end %>

(The c.vm.guest may not be needed)

Is that expected? I tried using your tk-windows and tk-multiplatform but they didn't work out-of-the box without this change, too.

Ciao!
