Resolved:
remove unwanted actions in theme’s functions.php:

// removes Quotes Collection plugin's CSS reference
remove_action('wp_head', 'quotescollection_css_head');

// removes Quotes Collection plugin's .js reference
remove_action('init', 'quotescollection_scripts');

Thanks for the offer! I’ll make a counter-offer, though. 🙂

How about changing $replace variable to

$replace = array (
                        'post_author' => 'get_the_author' ,
                        'post_url' => 'get_permalink' ,
                        'post_date' => 'get_the_modified_date' ,
                        'post_time' => 'get_the_modified_time' ,
                        'post_title' => 'get_the_title' ,
                        'blog_url' => array (
                                'get_bloginfo' , array (
                                        'url'
                )
                ) , 'blog_name' => array (
                        'get_bloginfo' , array (
                        'name'
                )
                ) , 'post_categories' => array (
                        'get_the_category_list', array (
                        ', '
                )
                )
                );

at application/controllers/rrsinjectionfilters.php?

That is, [post_categories] would implement get_the_category_list function (http://codex.wordpress.org/Function_Reference/get_the_category_list).
