Add es5-shim library v3.4.0

Browse source 
With skip function to bypass loading in modern browsers.

Add dependency on es5-shim to OOjs and OOjs UI, and json2 to the former.

The ES5 skip function simply asserts the 'use strict' feature, which
means that all MSIE9 clients will recieve the library, which should
mostly be a no-op but will increase the load.

* Source code
  https://github.com/es-shims/es5-shim/blob/v3.4.0/es5-shim.js

As OOjs UI isn't yet tested against non-ES5 browsers using this shim,
leaving the note about likely breakage for that one.

/*!
* Skip function for es5-shim module.

* Test for strict mode as a proxy for full ES5 function support (but not syntax)
* Per http://kangax.github.io/compat-table/es5/ this is a reasonable short-cut
* that still allows this to be as short as possible (there are no function "No"s
* for non-"obsolete" real browsers where strict support is available).
*
* Note that this will cause IE9 users to get the shim (which should be close to
* a no-op but will increase page payload).
