NVM takes a specific node version and installs the node package and
a corresponding compatible npm package.
We use it in a somewhat hackish way to install node/npm globally with
a pinned version, since that's how we actually want to consume node in
our development environment.
Other details:
- Travis CI now is configured to use the version of node installed by
provision; the easiest way to do this was to sabotage the existing node
installation.
- jsdom is upgraded to a current version, which both requires recent
node and also is required for the tests to pass with recent node.
This fixes running the node tests on Xenial.
Fixes#1498.

This reverts commit be93b6ea28.
Unfortunately, the newer jquery comes with a huge performance
regression affecting the hotkeys code, which has the effect of making
typing super slow.
Fixes: #1449.
`tools/test-js-with-node cover` needs istanbul to be installed in
order to work; we might as well install it by default rather than
having it be an extra step users need to deal with.
Of course, since this is only needed in the development environment,
this could suggest we want to fork/conditionalize package.json, but I
think for now it's reasonable to just install everything we use
somewhere -- the npm list is still pretty short and we have that issue
anyway with webpack-dev-server.
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.
