* Add a test for built file size
Adds a script test for building Blockly's compressed files and
checking their size to prevent unexpected increases.
* Update size for new changes
* Add full stop
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.
