This is an alternative PR to #168 based on discussion there.
Instead of fixing the loading of tough-cookie for npm v3, this removes the monkey patch for tough-cookie. The equivalent fix is part of a version of tough-cookie (v0.12.0) that is required by Zombie v2.0.0 and later. Zombie v2.0.0 or later is required by MinkZombieDriver.
This PR also fixes Travis CI testing for npm v3 (so that npm v3 is tested with Node.js 5).
