Port to drupal 6.0

I ran the coder (code review) module and made a few changes.

The remaining issues are:

bloginfo.module

      severity: critical Line 62: new hook_theme() function is required to register theme_ functions (Drupal Docs)
      function theme_bloginfo_block($description, $format, $author) {

bloginfo.install

      severity: criticalclick to read moreLine 6: A new schema API has been added in 6.x (Drupal Docs)
        switch ($GLOBALS['db_type']) {

      Explanation: This patch caused changes to the format of hook_install(), hook_uninstall(), and hook_update_N(). No longer are switch statements done on $GLOBALS['db_type']; instead, use the variety of schema API functions to perform table manipulation.
