vagrant-wrapper 1.2.0

Given Vagrant 1.1+ is distributed only via packaged installers, this Gem provides a wrapper such-that an existing Gem install of the older Vagrant will not take precedence on the command line in a bundled project. Eg. shell calls to 'vagrant' will use the packaged version. (NOTE: The version of the Gem does not determine the version of Vagrant it links to.)
