title: Drupal 7 change block subject in template.php
body: <p>I have a block in my page and that block has a title. How can i remove this title (subject) within template.php? I tried <code>hook_block_view_block_alter()</code> but it doesn't seem to work? I could add a space character in the block configuration screen but it doesn't look the right way for me.</p>
