Fix clickable links in TextMate html output

Right now for me running the latest RSpec, TextMate 2 alpha, Rails 4, and this bundle, when I run my specs and get html output in TextMate, the links are not clickable. I brought it up in rspec-core (https://github.com/rspec/rspec-core/issues/1276#issuecomment-33680781) and they pointed me here. This proposed change fixes the issue for me.

This code is the example_failed method inside the rspec-core HtmlFormatter, with the 'super' call removed, and the last argument on @printer.print_example_failed set to false (to not escape the html).
