Add CentOS 6.4 minimal templates.

Based on the 6.3 x64_86 minimal template with a couple minor changes:

- Install chef via the new omnibus installer (so the ruby definitions
are no longer explicitly needed).
- Update the ks.cfg "%packages" to match the defaults from a standard
CentOS 6.4 minimal install.

Minor pedantry: Location of windows Key in autounattend.xml

- add a link to the location of the windows key for the 180 day trial license
- users should override this definition in their own templates - except if using the trial version
- reordered the userdata section for all to alphabetical primarily so it is possible to compare
unattended files more easily
'#' is not a valid comment in windows batch files

Update ip.rb to use vmrun guestVar to get guest IP

Current code can only retrieve NAT or host-only IPs by polling nat/dhcp settings.
By using vmrun's guestVar command instead it's possible to retrieve IPs in all networking setups.
Forgot to strip the newline on the IP address.
