Title: Dir.glob does not support backslash as a File separator, even on Windows...

.... See http://www.ruby-forum.com/topic/2016734. My cookbooks directory is C:\Users\jdutton, so I can't run Vagrant without this fix.

I made the most simple patch that fixes the direct problem. If you want to refactor or generalize this more (as with FileUtils.mv), I will gladly test your revised fix :-)
