Title: add rake to gemfile for travis

I have been trying to set up the Travis CI service for this project.
Looking at the ruby specific docs page I see
'Travis CI runs rake by default to execute your tests. Please note that you need to add rake to your Gemfile (adding it to the :test group should be sufficient).'

So that is what I did.
