PhantomJS is missing Function.prototype.bind

PhantomJS is missing Function.prototype.bind:

• Function.prototype.bind is undefined ariya/phantomjs#10522
• https://groups.google.com/forum/#!msg/phantomjs/r0hPOmnCUpc/uxusqsl2LNoJ

So code which uses it fails to test. There is a workaround. Is there a way to include that somehow before all other code is run?

I am using such code for me:

if Meteor.isClient and /PhantomJS/.test window.navigator.userAgent
  # PhantomJS (used for testing on Travis CI) does not have Function.prototype.bind and pdf.js is using it
  # https://github.com/ariya/phantomjs/issues/10522

  if !Function.prototype.bind
    Function.prototype.bind = (oThis, args...) ->
      _.bind this, oThis, args...

The code from Mozilla didn't really work for me in all cases and tests were failing from strange reasons connected with how bind operated. This code made them work.
