Initial commit for gradle-dev/2FDZ6MQNPJQ

This is initial commit for task described at this thread: https://groups.google.com/forum/#!topic/gradle-dev/2FDZ6MQNPJQ

Here some changes in Javascript we may need to implement:
1. add reference (a) to test names and able to scroll into specific test output position on page
2. add expand/collapse button to each test in test output to collapse all other test outputs except current. This is useful if I want to investigate issues in exact test (and don't care about many others).
