Separate template logic from template functions.php

As written in the WordPress Codex, template/design should be separated from program logic.

Actually there are template parts hardcoded in functions.php:

if ( ! function_exists( 'fruitful_entry_meta' ) ) {
function fruitful_entry_meta() { 
?>
	<span class="author-link author"><a href="<?php print esc_url( get_author_posts_url( get_the_author_meta( 'ID' ))); ?>"><?php print get_the_author(); ?></a></span>

Typically this should be separated.
For example in an include file.

Otherwise if somebody wants to remove the author link from any post, he has to remove this function…
