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. This should resolve Issue #43
