(maint) Add Travis CI Support

This patch adds Travis support.  It also makes sure that `bundle install
--path vendor` works with `bundle exec rake spec`.

This patch should coincide with enabling Travis CI support for pull requests.
A build status image is also included in the project README.

 Puppet
 ======
 
+[![Build Status](https://travis-ci.org/puppetlabs/puppet.png?branch=master)](https://travis-ci.org/puppetlabs/puppet)

 Puppet, an automated administrative engine for your Linux and Unix systems, performs
 administrative tasks (such as adding users, installing packages, and updating server
 configurations) based on a centralized specification.
