Bug 1166901 - Get the UI tests running as part of the travis run

This merges the service and UI Travis configs, to get the Karma UI tests
running on Travis in the new repo. We can only set 'language' to one
value, however that doesn't matter, since nodejs is installed by default
and all the 'language: node_js' did was set a few default build cycle
steps - and we can define those ourselves manually.

We install the deps using npm install, ensure they are cached by adding
the node_modules directory to the cache list, get xvfb running for Karma
(see http://docs.travis-ci.com/user/gui-and-headless-browsers/) and use
|npm test| to run Karma using karma.conf.js.

The end to end tests (karma-e2e.conf.js) are not currently running, same
as before the repo merge.
