Change the linter in gulp tasks to be consistent with Code Climate results which are based on ESLint using .eslintrc options. However, defaults Code Climate rules are too strict, so turn as warnings the 'complexity' and 'max-statements' rules (other errors has been fixed). Note that the Gulp task name has been changed for `gulp lint`.

More information on building and testing can be found in [gulpfile.js](gulpfile.js).
- Use tabs for indentation, not spaces.
- Only change the individual files in `/src`.
-- Check that your code will pass `jshint` code standards, `gulp jshint` will run this for you.

- Keep pull requests concise, and document new functionality in the relevant `.md` file.
- Consider whether your changes are useful for all users, or if creating a Chart.js plugin would be more appropriate.
