Code

function template_preprocess_block(&$variables) {
  static $block_counter = array();

  // All blocks get an independent counter for each region.
  if (!isset($block_counter[$variables['block']->region])) {
    $block_counter[$variables['block']->region] = 1;
  }

  // Same with zebra striping.
  $variables['block_zebra'] = $block_counter[$variables['block']->region] % 2 ? 'odd' : 'even';
  $variables['block_id'] = $block_counter[$variables['block']->region]++;
  $variables['template_files'][] = 'block-' . $variables['block']->region;
  $variables['template_files'][] = 'block-' . $variables['block']->module;
  $variables['template_files'][] = 'block-' . $variables['block']->module . '-' . $variables['block']->delta;
