	[vagrant] Downloading with Vagrant::Downloaders::HTTP...
	[vagrant] Downloading box: http://files.vagrantup.com/precise32.box

Remove base box info from README
Merge pull request #1 from mlafeldt/config.vm.box_url

Download base box automatically if missing
tidies some code
documents next steps after building the box
rewords the README
documents that the base box is fetched automatically if needed
sets the VM hostname
rewords the requirements section [Fixes #2]

The preferred way to install Vagrant are system packages, so
remove the gem install command, and delegate installation
instructions to the page of Vagrant itself.
Ignore ./rails

This allows users to have a clone in their rails-dev-box checkout that
will automatically appear in their /vagrant folder.

installs node.js as ExecJS runtime

The Gemfile generated for new apps has therubyracer commented out

ExecJS picks node.js directly if it is installed in the system,
so new applications just work.
