* Update dependencies and remove outdated ones
* Add package lock file
* Add minified file
* Karma now uses headless browser to run QUnit
* Add to readme that node and npm install is required
* Update license info
* Add lint-new but don't use it in CI yet
* Source files are under src/
* js/impress.js is now generated, but remains part of the repo (so it just works)
* npm run build
* build.js uses buildify node module
* Break out navigation and resize plugins from core src/impress.js file
* core_tests.js and navigation_tests.js have more tests
* qunit_test_runner.html runs QUnit in a browser (without karma) and
provides a generic iframe based platform to test different presentations.
* copy qunit.js and syn.js into the repo. This allows qunit_test_runner.html
to work without any dependency on node/npm. (Karma obviously does need them.)
* Move jscs cli option to .jscsrc instead
