First commit of the heatmap branch
Update Protractor config to use Selenium v2.41.0

The latest build of Protractor ships with Selenium version 2.41.0. This
commit updates `test/protractor.conf.js` to use this version.

Please note that Protractor tests are currently not passing with
Selenium version 2.41.0. I'm not sure if this condition existed before
updating.
