 * Gravity Forms filter to allow the post body and textarea inputs to use the wp_editor
 * visual editor. To use wp_editor instead of default textarea, just set css class
 * to "richtext"
 *
 * @uses	wp_editor() 	Requires WordPres >= 3.3.0 for this function
 *
 * see http://codex.wordpress.org/Function_Reference/wp_editor for arguments to 
 * pass to the wp_editor() function. At the very minimum, you probably will need 
 * to pass some styles in 'editor_css'; otherwise the gravityforms styles and your 
 * theme styles will likely override some of the styles applied to the editor 
 * buttons and text.
