Remove title attribute from node titles in Garland

As recommended in http://drupal.org/node/445530 this issue is to remove the title attribute from node titles.

The title attribute merely parrots the node title, i.e. title="<?php print $title ?>", which apart from being redundant (does not add additional information
about the link target or context), its annoying for screen readers configured to read title attributes (gets repeated, thus is again redundant).
