Travic CI Intergation

I have setup Travis CI to work with the project. It is setup currently to go out, download all the excelsior node/ruby assets and preform the `grunt package` task. 

So it can test as far as to ensure the the project will build and create a zip file based on all our ruby and node/grunt configs. If the branch submitted is the `master` branch and it will then commit the zip file back to the master branch with a .lastBuilt file that is a simple Travis time-stamp and build number for reference.

Every other branch will simply run the test process. So we don't have anything super fancy right now, but this sets us up for more and better testing down the road.
