Adding Bundler Gemfile and .travis.yml
Merge remote-tracking branch 'upstream/master' into 3404_test_coverage
Revert "Merge branch '3402_tests' into 3404_test_coverage"

This reverts commit 86e17952768bb7c052cae68c5b94ecf28c251d9f, reversing
changes made to 33b46ee789760c6a3f8b262e86168b7d57003881.

We don't want this, because I guess requiring rubygems in Rakefile is an
anti-pattern, or something. Upstream now has a Gemfile, which solves the
issue of making the gems available in a better way.
