Use nvm.el

This is pretty low priority. The current technique of just specifying which node to use works really well.

In case someone needs a quick fix for this, I have something like the following in my .dir-locals.el:

((js2-mode . ((eval . (progn
                       (setq mocha-which-node
                             (if (boundp 'nvm-current-version)
                                 (concat (cadr nvm-current-version) "/bin/node")
                               (concat (getenv "HOME") "/.nvm/versions/node/v" (s-chomp (f-read-text (concat default-directory ".nvmrc"))) "/bin/node" )))
                       ))
;; other vars here...
              )))

Notice that I'm relying on this file being in the root of the project, the same place where .nvmrc is located.

@dcluna I've replaced default-directory with (locate-dominating-file default-directory "package.json") so it works from nested directories as well. I like the solution, at least for a while.

If you're using nvm.el, once this PR is merged, you can add something like this to your init file:

(add-hook 'js2-mode-hook 'nvm-use-for-buffer)

Then, leaving mocha-which-node as node will work if you've defined an .nvmrc file, without having to mess around with dir locals (particularly eval)
