* Add babel transform-class-properties to have static class properties * Upgrade Lexer and Parser files to use ES6 classes * Update eslint max line length to 90 character (more indent because of using ES6 classes) * Upgrade eslint and jasmin to support ES stage-2 features * Use static properties to place constants near their functions * Migrate all remaining sources to ES6 syntax * Increase eslint max line length to 84 * Remove non-babelified endpoint in dev server.js * Clean up server.js functions after removing browserified * Make screenshotter not to use babel endpoint as we babelify everything now
