Issue #43 - Travis CI integration

Hi all,

I have added a .travis.yml file to the root which allows for integration with Travis CI. Currently the script runs the tests/index.html and tests/index-amd.html sequentially. There is one unit test that I had to comment out in order to make travis integration work. It is due to relative pathing issues within Travis CI/Phantom-js.

Once OpenF2 is setup with Travis CI you'll be able to include the Travis Image to verify that the build is passing.

Feel free to shoot me any questions.
