- Removes deprecated, non-functional lint scripts
- Removes some unused (and barely used) dependencies
- Replaces deprecated `gulp-util` dependency
- Adds eslint rule to prevent future use of deprecated `gulp-util` dependency
- Moves all gulp tasks into `tasks` path
- Moves `gulp_helpers` into `tasks/helpers`
- All tasks in `gulpfile.js` were moved into `tasks` and broken up by domain
This is basically a no-op moving files around PR. All the existing tasks appear to work the same with these changes.
