This commit switches the Travis tests over to Travis's new
container-based infrastructure. It also tells Travis to
cache the node_modules directory for faster setup.
The latest version of Node.js has a bug that
affects the Karma test runner. A patch has been
merged to Karma, but has not landed in a version
yet. Until a new version of Karma is released,
we should keep node at 0.11.13.

(cherry picked from commit 9af2346a0cead634f3af5f390770ea65929c1f4a)
This adds support for Travis CI and SauceLabs
testing. Testing on SauceLabs in done via
the Karma test runner. Note that encrypted
Sauce username and access key values need
to be inserted into .travis.yml as global
environment variables. Additionally, the
local test runner (which is still useful
for debugging tests and code) was updated
to reflect that the 'node_modules' folder
now gets placed in the root directory.
