Replace individual .travis.yml commands and test_runner.js with tests/run_all_tests.sh, which manages the travis_fold statements and accumulating the output of all the test phases.
This script is now in charge of test_setup.sh (previously handled by npm pretest script). It also adds green/red color coding to each test section, based on success and failure.
* Changing root script for tests under Node.
Was: tests/jsunit/test_runner.js
Now: tests/test_runner.js
The webdriver & jsunit calls formerly in tests/jsunit/test_runner.js
are now in function runJsUnitTestsInBrowser, in
run_jsunit_tests_in_browser.js, called from tests/test_runner.js.
This makes room for additional tests under Node, such as headless and generator tests.
