added travis and fixed #93 

Note that travis will still not run correctly because of 
* jshint cyclomatic complexity and line length breakages (I removed jshint in my own repo to prove the travis ci/sauce integration). Saucelabs won't run till the jshint failures are fixed

* shared resources not present via the bower install i.e. https://github.com/ibm-js/deliteful/issues/93

Also note I added the `on_failure` notification which should also be added to delite, you only want to know when a build status changes.
