Created an "lxc sudoers" command to create sudoers file for a given user (defaults to current one).
Merge branch 'master' of github.com:jefmathiot/vagrant-lxc

Conflicts:
	lib/vagrant-lxc/plugin.rb
:scissors: whitespace
command/sudoers: Nitpick

* Use Ruby 1.9+ hash syntax
* Use % as the BOXES placeholder as it is the same symbol used for I18n placeholders as well
command/sudoers: Mention what is the default value for the user and add a REFACTOR note
Remove Vagrantfile from project root

We already have one for development purposes on /development and
`Vagrant.require_plugin` has been deprecated on Vagrant 1.5+
doc: Let everyone know about the new `vagrant lxc sudoers` command
