Rails 4.1.6. Java 1.8.0u20. Ruby 2.1.3p242. Increase default cpus to 2.

Finally got the correct Java version working. Updated to Ruby 2.1.3. Chris tested the provisioning on his Mac and it works on my Windows with all correct versions. All tests pass with the new Ruby. There should be no effect of the Ruby upgrade since it's patch level as stated on their main site. Heroku also immediately deprecated Ruby 2.1.2 so I take that as a sign that it should be fine. You will get a warning from gems it's using a different build number, but there's no issue.

This is obviously not urgent. I just stumbled across the solution while I was working on another project so I thought I would put it in.
