//		4. Override the configurations with the custom config file (if set).
//		5. Override the configurations with that ones set directly in the page code.
//		6. Load the editor skin styles CSS files.
//		7. Load the first part of tha main scripts.
//		8. Load the language file.
//		9. Start the editor.
