- Patch #11045 by Stefan: improved consistency of node modules:

  + made the helptext under the 'Explanation or submission guidelines', more the same (blog & story);
  + made the form_set_error() texts consistent when the body of a blog/story does not match or exceeds the specified minimal numer of words.
  + used the $options for form_select() and form_radios() inline like we do in the rest of drupal;
  + made the textarea sizes for the submission pages the same for all node types and also for the 'Explanation or submission guidelines';
