Fix for WP Plugin: 301 Redirects

// Fix for https://wordpress.org/plugins/301-redirects/
// Issue: Plugin CSS and JS files are enqueued on every admin page, not just the plugin settings page
// Edit from line 43 of 301-redirects.php:

function load_301_redirect_assets($hook) {
    if ( $hook === 'settings_page_301-redirects' ) {
        wp_enqueue_style( 'redirect_301_bootstrap_css', plugin_dir_url( __FILE__ ) . 'lib/bootstrap-3.3.4.css', false, '1.0.0' );
        wp_enqueue_style(  'redirect_301_custom_css', plugin_dir_url( __FILE__ ) . 'style.css', false, '1.0.0' );
        wp_enqueue_script( 'bootstrap', plugin_dir_url( __FILE__ ) . 'lib/bootstrap-3.3.4.js', array(), '1.0.0', true );
    } else return;
}
