Hide TinyMCE Icon From Visual Editor

Hello there,

I added a filter that allows someone the ability to turn off the icon in the WordPress Visual Editor. By default of course the icon still shows.

``` php
/**
 * Override Author Avatars tinymce configuration
 */
function mcl_tinymce_editor() {
	global $aa;
	remove_action( 'init', array( $aa, 'init_tinymce_editor' ), 30 );	
}
add_action( 'init', 'mcl_tinymce_editor', 10 );
```
