if you managed to find that code, then I don't think I know any more js than you do. But try this:

	        },{
	        	type: 'checkbox',
	          id: 'remote_file',
	          label: me.editor.lang.vbulletin.retrieve_remote_file_and_ref_local,
	          labelLayout: 'horizontal',
	          setup: function() {
		        	//if (me.editor.config.vbulletin.attachinfo)
				//	{
		        		this.setValue(true);
                                        this.disable();
				//	}
	        	}
	        }]
