Added 'load-grunt-config' plugin

The plugin replaces the custom 'loadConfig()' function with a more robust and extensible solution.

It handles 'grunt.initConfig()' and 'load-grunt-tasks'.

Changes:
- Moved Grunt task configurations into a 'config/' sub-directory to allow room for custom plugins, modules, and tasks to be defined without being included by the config-loader;
- Updated '.eslintrc' to better lint module-based JS;
- Updated EditorConfig recommendations;
