Use window.localstorage to loop through all unit tests.

Note that this commit introduces a js/yui3/build/test/test.js file. I hacked the
test.js file since it's loaded on every test page. The additions to the file mainly
revolve around listening for test runner events, appending test results to localstorage,
and navigating to a new test page once all tests on the current page are complete.
refactor code so test results are shown on the app after tests run
only show failing tests upon completion
Update README.md
remove reference to readableTestResults.js and results.txt from jsproj
