Install node dependencies using npm.

The node packages 'jQuery' and 'jquery' are different--'jQuery' is the
legacy support package that is needed for Zulip so the require statements
in the tests were updated.

Travis uses node 4.0 by default and we are using 0.10, so the command to
install the correct version had to be added to the .travis.yml file.
