[HTML5 Client] Initial Acceptance Tests Setup

[HTML5] String refs to callback refs

HTML5 - Chat links fix

This commit does the following updates:
- fixes the misprint that prevented Chrome from being installed
- removes the step of creating the `tools` directory (we don't need this anymore, since the directory is commited now)

This commit does the following:
- adds the Spec test reporter to display all the passed/failed test specs after all the tests finish running
- removes console logging (we don't need it anymore, since we can see the reported results at the end of every test run)
- adds the XML test reporter for easier Jenkins integration

String refs will be deprecated in the next React releases, since they have some performance issues
