Ignore packer-generated stuff
Add basic cetos-6.3-x86_64 converted from veewee template
convert cent6.3 to 6.4

- CentOS 6.3 has ships with a weird bug that makes `yum` unfunctional
- install "ruby-install" and "chruby"
- install a system ruby (mri 1.9.3) in /usr (process is havely based on postmodern/chruby/master/scripts/setup.sh )

stole some ideas from smerrill/packer-templates :

- add user "vagrant" as kickstart deploy-user
- add epel repo as kickstart option

- remove puppet in favor of chef (11.6.x)
- don't use puppet's facter to check on vich vm we are runnung (use lspci instead)
- use local .iso-files to install VMWareTools/VirtualBoxGuestAdditions

stole some ideas from hectcastro/basho-packer-templates :

- use symlinks to order common and distribution-specific installation processes
