Refreshed Gemfile.lock file

 * Rebuilt Gemfile.lock file to refresh Gemfile.
 * Used https instead of http in Gemfile.
 * Added minitest(3.5.0) to get green test run.
 * FYI: See 5 **deprecated and will be removed in 2.0** warnings.
 * FYI: Tests are not totally headless but it worked.
 * FYI: Here are other ways for me to help:  http://pastie.org/6582928
