Remove "jshint" dev dependency from package.json and the gulp task.

sh:

npm install gulp-eslint --save-dev

gulpfile.js:

var eslint = require('gulp-eslint');

gulp.task('lint', function () {
    return gulp
        .src(['./src/*.js', './src/cinemas/*/*.js', './tests/*.js'])
        .pipe(eslint())
        .pipe(eslint.format())
        .pipe(eslint.failOnError());
});
