Bump Ruby version to 1.9.3

OS X 10.8 doesn't have a build, and for some reason RVM doesn't want to build it from source:

	$ rvm install ruby-1.9.2-p320
	No binary rubies available for: osx/10.8/x86_64/ruby-1.9.2-p320.
	Continuing with compilation. Please read 'rvm mount' to get more information on binary rubies.
	The provided compiler '/usr/bin/gcc' is LLVM based, it is not yet fully supported by ruby and gems, please read `rvm requirements`.

Patches after Puppet Vagrant Boxes refresh work

This patch solves a number of problems I discovered when recently working on
refreshing the images on puppet-vagrant-boxes.puppetlabs.com.

* Changed Puppet installation to use packages for Centos 5.9, Ubuntu 10.04.4,
  Ubuntu 12.04.2, Debian 7.0 and Debian 6.0.7
* Separate setup scripts into separate pieces for Centos 5.9 like other modern
  templates
* Provided a new template for Debian 7.1.0 based on the Debian 7.0 one
