Allow 'Editor' to flush/purge cache

Hi,

Maybe it’s better if it stays the way it is.
If you want a purge sg cache for editor role, put this inside your functions.php file of your child theme:

add_action( 'admin_bar_menu', 'add_admin_bar_purge_editor' );
function add_admin_bar_purge_editor ( $wp_admin_bar ){
		$args = array(
				'id'    => 'SG_CachePress_Supercacher_Purge',
				'title' => __('Refresh website','sg-cachepress'),
				'href'  => wp_nonce_url( admin_url( 'admin-post.php?action=sg-cachepress-purge' ),'sg-cachepress-purge' ),
				'meta'  => array( 'class' => 'sg-cachepress-admin-bar-purge' )
		);
		if ( current_user_can('delete_pages') ) {
			$wp_admin_bar->add_node( $args );
		}
	}

Good idea. Please also include an option (or code snippet) to change the text of Purge SG Cache in the front end admin bar. None of my clients understands what this is :). They do understand refresh website or something like that. Also some people want this text in a different language for the clients.

+1 on editors being able to clear the cache.

Is there an action that can be hooked to purge the cache? In the meantime, it would be nice to be able to clear the cache using a custom option.
