Update Tern & Acorn (#11569)

* Update Tern -> post-0.13
Replace Acorn submodule with local copy
Update Acorn -> post-2.2

* Change function call for renamed function

* Load ecma6.json into Tern

* Workaround non-emittable options in acorn_loose

* Fix unit test
Since we only get 500 hints back and there have been many new additions,
Date's "getSecond" was no longer part of those 500. Thus, I decided to
check for the existence of hints from Function, String and Array instead
of Function, Array and Date.

* Make use of the correct, renamed Tern definition

* remove old acorn & tern

* add acorn & tern as npm dependencies

add lodash as dependency

* grunt install installs dependencies for extensions from npm

* fix acorn & tern paths

* load libraries from node_modules, not working yet

fix acorn to load it with requirejs

* forgot to add glob dev dependency

travis builds on node 0.10 which doesn't have promise

* add eslint-env node

* fix missing use strict
