add Chef-DK, remove Ruby and Omnnibus Chef installations, update DevKit for Chef-DK (x86)
move chefdk to a shorter path to reduce likeliness of hitting windows max path length when installing gems
update to vagrant 1.6.3, remove bindler in favor of individual plugin installs :-(
ensure we don't -fix- mess up the .dll and .exe files in chefdk/bin, ignore vagrant-application-cookbooks for now due to depenedency conflict
